That might be good. I hate the TE idea, but I like the flanker idea. Start out with him and Wells in the backfield (or even Saine and other Wells wouldn't be bade). Shift Saine out wide, and make a linebacker cover him. Then, either run Wells that direction (whichever Wells it happens to be) to take advantage of the side that is missing a linebacker, or throw a slant to Saine to take advantage of the mismatch in coverage. Or, if they move a safety instead of a linebacker up on Saine, bomb it to the wide-out on that side.
But if you want to do something to "shake it up," you have to get creative. As much as I hate this idea, I also love it, but bring Henton in the game. Have him play 75% of the snaps on offense. Sometimes he's the quarterback, and sometimes a receiver. Sometimes he's the punter. Heck, try him at tight end or something. And keep Boeckman in the game, too, when Henton is the quarterback.
