Due to the fact cooling will never be an issue, you can switch that MRM40 for MRM30+10 and enjoy an almost identical cooldown + duration of MRMs compared to cooldown + charge of the Gausses. Also, that build is quite short on ammo, so I've downgraded the engine and stripped a bit armor https://mech.nav-alpha.com/#45e54de1_COR-BR Still, MRM aren't very good at medium range due to spread and quite low missile velocity, so I'm quite sure it won't pair up well with gausses at medium-long ranges.
