okay actual fucking Persona question

How should I build a Trumpeter? I sort of want this White Rider to have both Mamudoon and Mahamon with Mudo Boost and Hama boost, but should I even worry about inheriting those over to the Trumpeter? Those skills with boost are extremely busted pretty much no matter which Persona has them, and I already have those on a few different Personas, as well as a few Megidolaons from Skill lvl up. So should I just inherit Growth/Invigorate/Null Physical and such to Trumpeter and call it a day?
