Is there any value add to putting a top wax coat over shellac or varnish?

Was going to hit my soft maple with BLO, then go the shellac or varnish route after reading up on some old threads. No real goal here other than to give this method a shot after years of loyal patronage of the Minwax stain/poly shelf.

I assume the BLO will help the curl pop out of the maple. Can't wait to try it tomorrow.
