Am I insane to try this?

Would have to do some testing if I raise it that high, the banner is 50', the ends would hang off the front and back...

wouldn't have to be that high, just enough to clear your board & banner lying on top....and then maybe nudge a bit to avoid any minor buckling of material.
anything thicker than the grommets, narrower than the space between them in the canvas area, and big enough to span the logos to be printed individually, would be ideal
...then just make target marks on the banner & table to slide across the openside between logo prints.

Just make sure to get a video of the attempt. I'd like to see how many 50ft banners it will take to cover the cost of a new printhead.
