Here's what I figured out so far:
The bms
Pokemon Gflxpack is from
http://aluigi.altervista.org/quickbms.htm.
You use the reimport.bat quite excatly like you used the export:
1. Choose bms.
2. Choose the same gfpak as if you would extract.
3. Choose the folder with your already extracted and changed content.
Quickbms will now try to implement the new content, but warns you if the size of a file is bigger than its original, which would lead to a corrupted gfpak if forced to do that.
After that, your chosen gfpak file is being replaced with the new, so make a copy of your original before.
I thought I could use this to model swap the main character with a npc like red/blue/green or the e4 but I don't know what files I should replace (if this would work at all like that).
If I simply try to replace all the .BNS, .BNT and .DAT files (by file-name) of the new model with all the files of the MC and then repack, the game always crashes at start
(Sorry I know this method is probably complete bs, I'm not that deep into this and merely tried to mess a bit around).
So I'm wondering if someone know how to make proper model-swapping if it's already possible at all?
Here's a thread somebody asked for that too but didn't receive an answer yet

I'd really appreciate if someone could lead a direction on how to achieve this!
