Baryancistrus sp. doesn't sound all that bad. I was reading about them and it sounds like they are shy and don't really mind other fish(except other types of catfish). At an average of 8 inches they aren't too big either. Even the PH is similar/close to what GFs likes. It also sounds like they don't attack other fish but prefer to scavenge for food and like to use algae as a protein source. Do you think it could work?
A whole bunch of site seem to all have slightly different info, like size and temperature of tank. Here are some articles I found.

Just pondering since I saw a 4 inch one at LFS. I don't really need it nor really want it but if it would work then I might get it since I would love a pleco. I fail at rubber lips. If you can give me some experience info on keeping them alive, I would appreciate it. I've read articles but they don't really help.
