All mainly close counters but yes those are somewhat viable.

On open land, which there is a lot of in this game, the scout can easily be king and then it can still go steam roll almost anything but a heavy in CQC using a SMG without changing fittings. This is an example of the issue I have. If you want to be the best in CQC you should have to give up the ability to be the best in mid ranged combat and vice versa. In the current enviroment that is simply far from the case. Between strafing ability giving an advantage even with a lesser weapon, 2 equipment slots, and extreme visibility something has got to give.

I hope this clarifies my argument towards only one light weapon slot. I feel like this is the easiest and most balancing thing that could be done to the scout without over nerfing it or really hurting the true scout who fits his suit to a single role and capitalizes on his advantages.

Sign... but make sniper rifle a sidearm even though we all know its a light.

no thank-you light frames were originally sniper role. how would you fit a sniper or are you going to make that a sidearm?

IMHO Scouts should have one light weapon slot. This would force them to commit to their role.

Something just really needs to be done about the fact that a person in a scout suit can run multiple styles without ever changing suits. Currently a cloaked shotgun scout with an SMG is free to switch from stealth shotgunning to strafe spray and praying instantly and even carry his own ammo. Why is it that everyone went crazy over slayer logis being able to run multiple styles and excel at all of them yet scouts have experienced the same thing while at times also being far more OP than the slayer logi ever was?

Every suit is meant to have a counter but how do you counter someone with one suit when they have the ability of two or three.

Minmatar Assault
X2 Complex kinkats
X1 Shotgun
???
Profit!

Ew. What about poor Minja? What happens when said frame runs into enemy when enemy decides to check his six? Said scout will be dead. A full Proto Minmatar Scout even with a Light Weapon and Nova Knives will die fast. Shield tank? Yeah, to get an EHP of 300. Armor tank? Can't run with plates. Now you're forcing Minja's to either run Nova Knives by themselves or a random gun. I would like you to try to run Nova Knives by themselves.

Shotgunners and SMG is not stealth shotgunning to spray and pray. If a shotgunner misses, the enemy will immediately whip around, backpedal, and fire with whatever weapon. And if you were stealth tanking, you're dead.

The SMG is not a long range weapon that transforms a stealth shotgun into a assault. A stealth shotgunner has very low EHP and with an SMG he's better off running away. Scouts are squishy. It's not a complete change of roles. He still needs stealth to use the SMG effectively if he stealth tanks. If armor tanked and shield tanked, he might as well run a good Light Weapon and Sidearm.

Thus, scouts can't change roles with a swap of a weapon. They need to hit up a supply depot somewhere to change.

Counter? Counter to scout is simple. If he is tanking, back up, and fire and strafe. If he is strafing, toss a grenade at the ground and get him to go away. Use area denial weapons like flaylocks and mass drivers to keep them away. There are many counters to scouts.

Or, you could address the problems causing the Scouts to outperform other suits as opposed to making a change that is not only unnecessary, but an awful idea for reasons stated in the last time a "sidearm only" nerf was suggested.
Lets look at all of the problems that would be addressed:

Scouts w/Combat Rifles

Now lets look at all the unnecessary playstyles that would be removed here:

Scout w/Plasma Cannon
Scout w/Mass Driver
Scout w/Sniper Rifle
Scout w/Plasma Rifle
Scout w/Laser Rifle
Scout w/[Insert anything other than Combat Rifle here]

Moving the shotgun would pretty much equate to every Medium Frame and their mothers, brothers, grandmothers, and next door neighbors carrying Shotguns in their Sidearm slot. This is bad because it would give suits capable of moving over 7m/s incredible ganking power with no actual sacrifice. (Just picture a Six Kin ACR with a CreoDron SG at 7.5m/s and 500HP of shields).

The real problems with Light/Scout Frames:

Possible eHP ceiling is too high
No firing delay on clacks
Lack of incentive to use Assault Frames

Now tell me, which problem(s) would be addressed by revoking their Light Weapon Slot?

Damage mods only apply to one of the two weapons if I am correct
