Why not learn to apply polyurethane and skip the lacquer? Yes, it will
take longer to cure increasing the likelihood of dust nibs but the sandwich
you are asking about is asking for trouble.

How much water are you talking about? Lacquer has moderate water and
water vapor resistance, poly has pretty good resistance.

Good Luck.

I've been trying my hand at veneer inlays. Deft spray laquer seems to
give
a great looking finish, but I doubt if it would stand under wet drinks.
Any
ideas as to how polyurethane as a protective top coat would bond to a
laquer
finish
