Board size and volume and catching waves

Hello,
I know posts like this are a dime a dozen. I currently surf a 9'2" longboard and was thinking I want something in a smaller form factor just for easier transport. I like having a big board for stability and catching waves, so I've never veered from it. Is this possible?
I'm 6'1" and 215lbs, is it possible to get a 7 foot board that I can grab waves with? I've been looking at something like a firewire dominator but was wondering if it would change everything and make catching waves hard. I'd also like the possibility of duck diving.
