how about cutting 2 signs out of 3/8 lumber - one reading ADAM and the other MAYA - then glue them together back-to-back? They could sandwich a dark backer if you want to keep them separate. Then you can use the heart if wanted, or not. You could stack them for the A, A, M to keep them aligned, then separate to cut the D and Y.
This could also work with an inlay of the letters. Using anFDUR#1 blade (0.011 thick), to get 3/8" to inlay flush, cut at about 1.7 degrees. Or 2 degrees to keep it a little proud then sand it down.
