I *LOVE* that exploding jetpack idea!
(And this from someone who plays quite often as a clone jet-trooper!)
We do really need some difficult-to-achieve "special moves" to spice things up beyond the run-and-gun fare...
Other notions :
1.) The ability to kamikaze a mobile command point's "vulnerable spot" with a fighter and take off 50-75% of their hit points in one fell swoop. (Thinking snowspeeders through AT-AT viewscreens, LAAT's against Spiderwalker viewport, etc.) It'd be risky as you'd have to build up speed and fly in the face of the pilot's forward pointing gunnery, but it would be *really* special if you pulled it off.
You could even randomize the damage to make the outcome a bit more unpredictable.
2.) Modify the existing LAATs so that they can air-lift/drop ATTE walkers. For Republic troops it'd be an amazing team effort — you crew the walker and the gunship, then the LAAT pilot moves in low overtop of the ATTE and hits the "g" key to pick up the walker. Off you go, but flying slightly slower than normal due to the payload (with the command post disabled as a spawn point while it's in the air.) If you pull off the maneuver, you move the command point across the board much faster and deploy it in a key location. If you happen to be the TradeFeds and shoot it down, that's pretty special too as you've taken out a command post, a ship, and about 8 clones — it'd be tons of fun for *both* factions!
Elements of skill and chance really add spice to a battle...
Great risk for great reward.
