Say the UAC weapons function like a mini-gun. Give it a 2 second spin up time, and a barrel cool down time of 5 total seconds for full cooldown. This is completely divorced from heat sinks as it's to balance the engagement windows of UAC's against AC's and it can be tracked with an indicator bar on or above the weapon groupings area.
I would set it up so an UAC in a weapon group starts spinning with the first click, starts firing with the second click and shuts off with a third click and then starts cooling off. This works with the weapon grouping system in the game and doesn't involve multiple buttons to control the weapon, just it's own weapon group.
So an AC5 can fire every 1.5 seconds for 5 damage. A UAC5 spins up, and then fires a 3 damage shot every 0.5 seconds that you hold the button down after the 2 second spin up time. Having the barrel spin doesn't build barrel heat, but also doesn't let the barrel cool off. So you can prep-spin, but you have to wind down to ready the next burst.

Note that the two stay in fairly tight lockstep for overall dps over time, but are used in very different ways, and would have a very different feel in game play each with their own pros and cons.
Also note at the 4.5 to 6 second mark (4 to 5 AC5 shots) the weapons are doing about equal damage. So for short firing engagements they have rough parity. The UAC5 user gets a heavy benefit for staying engaged for the additional 4 to 5 seconds, but then would want to be looking for cover at the end of it with a 7 second break (5 seconds of cooldown and 2 seconds of spin up) about to happen.
The barrel heat mechanic linked to the barrel spin up ensures that a player isn't going to pull more dps out the weapon over time than is intended, so macros won't benefit anyone.
Thoughts?
