The EZ30R (the R is important) and EZ36R both weigh ~50 lbs more than a DOHC EJ, so I doubt the handling would be effected all that much. The H6 engines aren't particularly expensive, you can find EZ30R's in the $1500 range if you look hard enough. Very few people bother swapping them into Imprezas, so there isn't a lot of demand driving up the price. The big downside is that the OEM H6 ECU has some sort of anti-theft feature that makes it a worthless brick, so you'll need to buy/install/tune a stand alone ECU.
If you have the tools and don't mind doing your own wiring/tuning, you could probably swap one in for < $3000. If you sell your stock motor, you might even come out ahead. Getting more than ~270 bhp out of one, though, is going to burn a crater in your wallet.
