I would anticipate problems, Lustercote is an enamel, or Urethane I believe, and as such it is fairly intolerant of solvent reintroduction. Laquer is designed to build adhesion from solvent penetration into the substrates. i would anticipate that if you spray the laquer over the lustercoat with enough material to stick, it will lift and craze the lustercoate, and if you spray the laquer so it doesnt craze the lustercote, it will not stick or be glossy.
My opinion, but somethimes you can get away with stuff you shouldnt,,
