Wait, you have a sprite for the main character wielding a different weapon? If the player is the only one who use those sprites then you could consider using GCOPY and keep the sprites that you're using on the sprites page(The rest could be on other page).
For example, I've modded Jump Edit+ to make it ressemble Mario Maker and did the same to change the skin of the player.
