The cab is going to impart it's own tone to a large degree. The Peavey's poweramp will also impart it's own tone as well. I'm quite confident you won't be impressed with the results.
I'd suggest run a neutral poweramp into your cab, or best yet run a neutral poweramp into some kones.
The cabinet is going to be responsible for at least half of your tone, so the Kemper's versatility will be lessened to a large degree running through a guitar cab. However, most profiles will sound good through V30's imho, just accept whichever speaker you go with is going to be the colour of all your profiles
