No worries my friend, for raising up your F6F-3 (x2) and F6F-5 to MAX, you will need 24 copies either way.

(And more if you plan to make extra copies of F6F-5 and upgrade them to MAX, which is actually a good investment considering it will have great stats, though if lacking Shiden Kai Ni, it's going to take quite a while...)
