That said, I think IS auto-cannons should get a similar workup, but adjusted to keep them slightly better for their weight.
My solution is simple:
Have the IS Autocannon projectiles be 100m/s (or more) faster than their clan Ultra counterparts. (which I think is already the case, at least in the 20's department)
Have larger bore sizes for IS weapons. (Fits the weight increase, right!?)
Weapon----CLAN----IS
(U)AC20------5--------3 (Shells)
(U)AC10------3--------2
(U)AC5--------3-------2
(U)AC2--------2-------1
This would better allow for the straight brawl-y fun we had in the PTS, while keeping the IS Autocannons better at concentrating damage to off-set their weight and size disadvantage.
(And would also severely cripple much of the poptart meta, along with the JJ/legdmg adjustments.)
------------------------------------------------------------------------------
It is my hope that this would be merely a stopgap measure, on PGI's way to making individual variants of weapons. (Different manufacturers: different characteristics.)
Example: AC20
Chemjet 185 = 2 Shells at 700m/s
Pontiac 100 = 3 Shells at 900m/s
Luxor Devastator-20 = 10 Shells at 1400m/s
And so on, and so forth. (You could even make them faction specific for CW)
Each would have advantages and disadvantages. (For a visual demonstration, look for Koniving's video, he put words into pretty film.)

EDIT:
Alternate proposed solution:
Maintaining singular large projectile (to maintain a more significant flavor difference and IS survival tactic) that has arcing damage similar, but to a lesser extent, to the CERPPC. (Main damage + 1-2 components arced to.)
AC2 = 1
AC5 = 3.5/0.75/0.75
AC10 = 8/1/1
AC20 = 16/2/2.
This allows the FLD to be maintained (for above stated reasons) but increases the TTK on smaller mechs by keeping that SHD with 36pts of arm armor or 40 pts of left torso armor from eating a full 30pts of damage in one click from the PPC/AC5 meta build. (And increased survivability for everyone else, but more especially light mechs.)
