J,
Only problem with that is the aztec masks are designed for a specific kit, and line up accordingly. It'd be very difficult to get them to 'fit' another kit.
For $30.00 you can get the 1/1000 scale NX-01 Enterprise and a set of Aztec Dummy masks for it, and learn how to work with these masks. If you screw it up, well the worst you're out is $15 for a new mask, and you can overspray or strip the kit!
