The idea is that all weapons can be divided into roughly 3 categories: small, medium, and large. Small weapons could include things like small and medium lasers, machineguns, SSRM2, SRM2, LRM5, and maybe SRM4 or AC/2. Medium weapons could include large lasers, AC/5, SRM6, LRM 10, and maybe LRM 15. Large weapons would be PPCs, AC/10 and 20, LRM20, weapon systems that are very big (volume/crit slots) and very heavy.
Each mech would have a mixture of differently sized hardpoints, which is unique to each mech but would generally trend from smaller hardpoints at lower weight to larger hardpoints at higher weight.
An example of this system in action is the Hunchback. The H variant has one ballistic and 5 energy hardpoints in the current system. It's stock loadout is an AC/10, four medium lasers and one small laser. With sized hardpoints, that would be on large ballistic hardpoint and five small energy hardpoints. This would allow the exact same customization. On the other end of the spectrum, you have the Stalker. The 4F variant comes stock with 2 LRM10s, 2 SRM6s, 2 Large Lasers, and 4 Medium lasers. This would translate into 4 medium missile hardpoints, four small energy hardpoints, and two medium energy hardpoints. This would restrict the customization, making the current PPC cheese builds impossible without any weapon nerfs. Because the mech is intended to have medium laser sized weapons in the arms, trying to cram
PPCs in will not work. An exception could be made to class Large Lasers in the same rank as PPCs, but this would still only allow two, and on the torso instead of arms.
TL;DR
This system would still allow a wide range of customization, while restricting the worst cheese. It would also breath new life into the current system of variants, by making the actual loadout of the stock variants a serious consideration, instead of just trash to be immediately rebuilt. Player would buy variants because they provide unique advantages and disadvantages, and in many cases there would no longer be one "best" variant for each mech. Finally, It would encourage less boating and more balanced builds. Most players agree that large weapon boating hurts the game, and under a size hardpoint system very few mechs would have the ability to carry more than two or three of the same large weapons (read "PPCs").
