Good idea, but the issue is not necessarily that alpha strikes are possible, but that there is no real limit to the things you can boat.
A more balanced solution would be to reduce the heat cap (either by removing the base capacity, or to remove the additional capacity of heat sinks. I would say the latter is the better option), and increase heat dissipation by
75-100% 60-150% (depending on the method used and possibly what the base is changed to). This would leave alphas possible, but impractical for large groups or hot weapons.
With a heat cap of 20, 2 ERPPCs simutaneously would overheat any mech). So a mech could still fire 5 ML without overheating, but not 2 ERPPCs. Due to heat dissipation, one could fire three LL, 7-8 SL, 5 ML, 2PPC, 1ERPPC, etc.
Assuming PGI keeps their boating penalties, this can also eliminate the dual AC20/Gauss builds (and if they're smart, Gauss+AC20 too).
