I agree with many of the previous posts. Setup and an HPF could get you part of the way there.
Physics will prevent you from getting all the way, though. You're asking a lot of one little speaker.
My advice?
Sell your combos. Both of them. Go out am get a very compact head. TC makes some. Trace Elliot Elf seems to get a lot of praise. The Elf would literally fit in the pocket of your gig bag.
Then get about the tast of getting one or two VERY lightweight cabs.
Here's the thing about cabs amd cost. Light, loud, cheap. You can pick any two, but not all three.
If it's loud and cheap, it will not be light.
If it's cheap and light, it will not be loud.

Get a Mesa Subway 112. Then save up for another if you think you need it. I did that with the 115. Now I take 1 toast gigs, and 2 to gigs where I need stupid amounts of volume.
Modular is the way to go. Worst case, you run back to the car to grab your second ridiculously lightweight cab.
Just my two cents. Best of luck either way.
