If you transfer the logic board and Touch ID cable together, it should work. However, based on the colors of your phones, if you put the 32 GB board in the gold phone, you'd have to take the silver Touch ID sensor with it, which would create a mismatch.  If you want to buy another 32 GB logic board to replace the 16 GB logic board, you won't be able to keep Touch ID functionality.
