I'm not sure why you would bother to restrict anything other than PPC, Gauss and AC20. Basically you just give select hardpoints the special designation of being able to mount those weapon systems.
Those are the three big deal weapons that any mech from lore that uses it was designed around the weapon system.
You could literally leave everything else as is and just take away the ability to boat those 3 weapons and you'd achieve 90% of what you are looking to achieve.
That approach has some serious drawback though, because it just means that double gauss mechs will always be extra strong and extra special but you know what they are going to be good anyways so I'm not sure how much we've lost.
Not sure what that does to clan mechs, they probably get much stronger in relation to IS mechs as boating lasers and lower caliber AC's is strong for them anyways. We would ditch the really annoying FLD metawhales and other C-Gauss builds though I think for the most part.
Effects:
Jagers can't use AC20 or Gauss anymore. They are now just as bad as every other IS heavy. Almost. High arms are still high.
The Protector might be good even though its low arms are terrible. Its a bad Dragon Slayer Jr.
K2 can mount 2 PPC's this is an extra special thing.
Awesomes with multiple PPC mounts are special.
Vindicators and HBK's and Cents that are designed around AC20 or PPC might make a bit more sense.
Stalkers can't PPC boat anymore, not that they do anymore anyways. I think the Misery loses the ability to mount AC20?
CTF's can't gauss anymore until 3060 and the can only mount single PPC. They are probably still quite good thanks to hardpoints and will swap down to AC10 and/or LL. If they regain some pop tart abilities from the jj changes they'll be fine most likely.
The Dragon Slayer is basically even more broken and special than it was.
Cbill VTR's can't mount PPC anymore. So RIP those builds.
Basically Gauss, AC20 and PPC become much rarer sights on the battlefield. The game becomes more laser warrior online, which is good because lasers don't do FLD and are weak against twisting and moving targets and require a lot better aim to maintain top damage. Pilot skill is more important.
Maybe/Hopefully single Gauss becomes not a "bad" setup.
Obviously only builds are lost in this setup as opposed to the argument that changing to a MW4 system adds a bunch of build variety if you want to make every mech a 13 small laser Nova-style atrocity.
