It's possible that it would work. If you did it right, you could also get the same effect from cutting 45* grooves into an AM Lunacy wheel tread.

Some time ago, while I was still on a team, my dad and I did a VEX-scale prototype of a rather slick mecanum-pattern drive. There were no rollers involved. Not only did it turn well, it acted like a mecanum in terms of sliding. We never did go full-scale, though, so I don't know if it would work in FRC.

The original intent? Make turning easier. It did have that effect. You don't need mecanum code, either, IIRC. Just the right roller orientation.

If you've got any mecanum wheels laying around, do a quick test with the KOP sticky wheels and the mecanums in a KOP frame, standard drive code, all that sort of thing. That's the only way to tell for sure.
