ROM Hack Trying to mod SM4SH & Project Mirai DX

[whiteglovian]

But I have no clue how to download models properly and forgot the LayeredFS method for o3DS
I want to convert .PMD and .PMX models to .BIN, but have no way of doing so. As for Mirai, I would adore if I found a way to replace movements for songs(Camera and motions) with .VMD to .BIN files. With this, you can see that i am working with MMD for models and motions.
I need help with model replacements for SM4SH:
SM4SH Models:
Lucina = MEIKO
Lucina(Yellow) = Neru
Lucina(Black) = PD Miki
Marth = CoolMedley Len
Zero-Suit Samus = Yowane Haku
Shiek = Meiko V3
Zelda = Kasane Teto
Ness = Chibi Yokune Ruko
Dark Pit = Kaito
Dr. Mario = Rummy LEON
Little Mac = KIO Leon
Peach = Hatsune Miku
Villager(3-ponytailed)= Rummy LOLA
Pit = LAT Galaco
Robin(Male) = Kagamine Len
Robin(Female) = Kagamine Rin
Palutena = Megurine Luka V4x
Wii Fit Trainer(Female) = Miku Append

I also want to make music replacements for Mirai, I'll do that myself, but I REALLY need help:

Deep Sea Girl = Circus Monster Miki cover
Finder = Persecution Complex Cellphone Girl(Ruko)
Sweet Magic = Poker Face(Gumi)
Animal-Fortune Telling = Karma(Rin)
Terekakushi Shishunki = WAVE(male cover, models are Yokune Ruko, Len, and Kaito)
World is Mine = Wildfire(Gumi)
Amatsu Kitsune = Panda Hero(Miki and Len)
Matryoshka = A Miki version of the song.
Skeleton Orchestra and Lilia = my Miki cover
Common World Domination = a Miki cover
