I'll bite.
[EDIT] Changing this to read as weapon class sizes - not crit or slot sizes.
[EDIT] Hardpoint limitations idea is by no means new. I found this poll by searching the forums. People seem to like the idea over ghost heat 4 to 1

[EDIT] Added a Stalker study of builds that would disappear and still be viable at the bottom using the hardpoint system outlined here.
So, I've gone through several mechs and fixed this. The idea is to limit hardpoint sizes. For example, the Catapult K2 has a ballistic slot in its side torsos. Instead of just being ANY ballistic, it has a ballistic slot of class 2. Meaning it can ONLY carry an AC2 or MG in the side torso. With this in mind, I'm studying several mechs with every variant for variation and removing problem builds.
Using this method, here is an energy class chart
[CLASS 1] - Small Laser, Small Pulse Laser, TAG, Flamer
[CLASS 2] - CLASS 1 + Med Laser, Med Pulse Laser
[CLASS 3] - CLASS 2 + Large Laser, ER Large Laser, Large Pulse Laser
[CLASS 4] - CLASS 3 + PPC + ERPPC
For Ballistic Weapons:
[CLASS 1] - MG, AC2
[CLASS 2] - CLASS 1 + AC5, UAC5
[CLASS 3] - CLASS 2 + LB10X, AC10
[CLASS 4] - CLASS 3 + Gauss, AC20
For Missile Weapons:
[CLASS 1] - SRM2, SRM4, Streak SRM2, LRM5, Narc, SRM2wArt
[CLASS 2] - CLASS 1 + SRM4wArt, SRM6, LRM5wArt, LRM10
[CLASS 3] - CLASS 2 + SRM6wArt, LRM10wArt, LRM15
[CLASS 4] - CLASS 3 + LRM15wArt, LRM20, LRM20wArt
[EDIT] - Also note that although dual AC20 Jagers, Quad and Hex PPC Stalkers, and Splatcats aren't a problem right now, they'd be a problem again if Ghost Heat disappeared.
First case study:
Stalker.

If you notice, ALL stalker stock builds are maintained but there is greater diversity among the stalker variants. Also, LRM boats and energy boats are removed.
[EDIT] List of builds that would disappear and remain. Obviously this is not exhaustive, but I think you can get the idea that it isn't killing diversity but rather keeping the flavor of the Stalker and encouraging the use of other Stalkers and even other mechs.
Stalker builds this will destroy:
1) LRM boats higher then LRM50
2) Artemis LRM boats higher then LRM30
3) laser boats with more 3x or more(ER)(pulse)Large Lasers
4) PPC boats with 3-6 PPCs including:
5) 2 PPC with anything including:
*2 PPC, 2 Large Pulse
*2 ERPPC, 4 Streaks
Stalker (3F) builds this will keep:
1) LRM50, any mix of 6x(Small)(SmallPulse)(Med)(Flamers)(TAG)
2) LRM50, 2x(ER)LargeLaser
3) LRM30wArt, TAG, 5x(SmallPulse)Med laser
4) LRM30wArt, 2x(ER)LargeLaser
5) LRM30, any mix of 6x(Small)(SmallPulse)(Med)(Flamer)(MedPulse)(TAG)
6) LRM30, SRM12 + any mix of med/small energy weapons
7) SRM24, + any mix of 6x med/medpulse/small energy weapons
8) SRM24, 2x(ER)Large laser + any mix of 4x med/small energy weapons
9) SRM20wArt + any mix of 6x small energy weapons
10) 2x (ER)(pulse)large laser, 4x med (pulse) Laser
11) 2x (ER)(pulse)large laser, SSRM8, any mix of 4 med/small energy weapons
12) 4x LRM5wArt, any mix of 6xmed/medpulse/small energy weapons
etc...
differences between some Stalker variants:
Stalker 3H
* Can carry LRM60 max (10 more then 3F)
* Can carry LRM50wArt (20 more then 3F)
* restricted to only 4x Med Lasers and no Large lasers
Stalker 4N
* can carry LRM40 max (10 less then 3F, 20 less then 3H)
* can carry LRM40wArt max (10 more then 3F, 10 less then 3H)
* can carry same lasers as 3F
Stalker 5M
* can carry LRM55 max
* can carry SRM28 or StreakSRM10
* CT (ER)(Pulse)Large Laser
Stalker 5S
* same as 3F but 2 AMS
