grain vac to fill bins

Hey everyone we are looking to tie our old dryer into our new system. Our new dryer fills bins with a dmc transfer air system we were thinking of adding a second air system but then got to thinking if we could use a grain vac so we dont need to spend a lot on wiring plus we would have the vac for clean up etc. Has anyone done anything like this and how does it work? It is only a 1000 bu batch dryer so we only need to move 250-500 bu per hr to keep ahead of the dryer. Also will they move wet corn? If so we would possibly use it to fill the dryer Thanks guys
