If you have the typical simulated faux wood with a paper coating, you don't want to sand it. The coating is thinner than paper thin and it's hard to get anything to stick to it.
Painting the doors would be the easy part. See if you have a hidden piece of the faux wood and test some paint, primer or adhesive on it. Perhaps try someone like a Benjamin Moore for suggestions. Even if you could get some type of adhesive wrap to stick, it would be time consuming to get clean joints. You sure don't want to start something and then find out it's not working.
I bought a few 8' lengths of 1x2 of faux wood from our dealer for some custom cabinets I built in the bedroom. The core wood is Ch*nese junk wood with an extremely thin paper coating that just *looks* like cherry. Even with a freshly sharpened blade in the table saw, it was hard to get clean cuts. Not nice stuff to work with. On our old TT I tried just about every glue/adhesive known to mankind on some of the faux wood plywood and it would not stick whatsoever. It's too bad pretty much all RV manufacturers use a wood finish for interior cabinetry instead of solid colors.
