Futari Wa was already dubbed, under the name Pretty Cure. That's probably the reason why the new dub is called Glitter Force instead of keeping the Japanese name.

As for the music, they'll treat it the same way as Digimon and Power Rangers. None of the Japanese Digimon or Super Sentai music gets used, so the same will happen with Glitter Force.
