I have not personally tried this so I can't comment from direct experience.
I've checked this out w/ a Carvin DCM 1000 as the power amp, into a Bergantino AE212 and also (in separate trials) a Schroeder 21012L.
Q: Will it sound like a WA?
A: Yes. The WA DI into a power amp into capable cabs will sound like the WA head's into those cabs, except with as many watts behind it as you need. Note that the cabs will have their own sound.
Q: Is it giggable?
A: With the right cabs, yes.
In a light Gator 4u rack, the WA + DCM 1000 is about 40 lbs. Of course, that power amp alone is ~20 lbs, so one of the crop of light power amps would shave about 12 lbs off the total weight.
You'll need some way to get the DI to FOH. (The DCM's input block offers an XLR link output, so I can send a post-eq DI to FOH from there.)
For me, though, this has stopped at the level of testing in the rehearsal room. At the levels I've needed for gigs in the last couple months, a WA head into either the Berg or the Schroeder covers my stage volume needs. Pushing 1000 watts bridged into either of those cabs doesn't really buy me anything I need.
However, I could see racking the WA with a power amp in two situations:
1. If I were running a fEARful at high SPLs.
2. If I wanted a low-gain WA tone at higher SPLs.
