I don't disagree with the conclusion of the OP that trying out a lower threshold and a higher dissipation would be interesting, but I did want to say that those decisions do exist in the game at the moment if your weapons and weapon groups are set up such that you're able to make them.
I have a Catapult with 2 Large Lasers, 2 Medium Lasers and 2 SRM6. I can't fire all of those in a fight very often before overheating, but my decisions are more complex than "do I stay or run while I wait until I can fire them all again?" It feels more like a priority process that takes heat into account along with range to target and how easy it's going to be to hit with the different weapon systems. In other words, given I'm limited by heat, which weapon system am I best off firing?
- If the target is at point blank range and fairly slow, I'll prioritise the SRM's and spend any left over heat on the lasers.
- If I'm unlikely to hit with the SRM's, I'll switch priority to the LargeLs and fill in with the MedLs if I have any heat left over.
- If I'm really screwed on heat, I might just use the MedLs instead of the LargeLs as I know they give better damage per heat.
- And obviously out to longer ranges I'll just be using the LargeLs.
(that's the theory anyway; I normally end up pushing all the buttons and overheating

)
Anyway, my point is that you can already play the game making the kind of decisions the OP describes, and I'm not convinced that just changing the heat system would be enough to make people play that way. Fundamantally, it's always going to be easier (and therefore more efficient for more people more of the time) to boat lots of similar weapons and simple make the "fire or not" decision instead of anything more complex.
As an aside, I wonder what the average number of weapon groups set up on a mech is? I'd like to think it was two or three, but suspect it's one.
