I would leave the staples in.
1) Stainless steel staples will not be super reactive with aluminium. Set them in just a smidgeon. Or, if you are using VHB tape to secure the aluminium, run the tape over your lines of staples. Or make sure your polyurethane or epoxy sealer has well covered the staples.
2) For galvanic corrosion to occur, you need an electrolyte (sort of). Not planning on having the aluminium skin let water in, are you?
3) The moment you remove the staples, you are relying solely on the glue layer between the veneer that is glued to the frame and the next veneer.
What I mean is, you may have glued your ply to the frame with the best adhesive on the planet, but the bond is only as strong as the glue layer that holds the face veneer to the next veneer.
Opinion of course, I have never clad a TD in aluminium so no experience to backstop my (somewhat) informed guesses.
