Bedrock Inventory GUI

Hi there! I need a little help with my already made texture pack or just make a completely new pack altogether. Does anybody know how to create a bedrock texture pack that only changes the inventory GUI? Like legitimately nothing else, not even that weird jcrafting book at the left side, only the inventory itself w a png texture? I need a godsent person rn im insanely inexperienced and DESPERATEE for this whimsy look 💁‍♀️ I already have a pack that overhauls the inventory and applies a texture ( see 1st pic). But annoyingly, it also changes the textures of other containers like the barrel or crafting table. Is it possible to keep my already made pack and remove the files that overhaul the other containers so it’s just the inventory left? Or would it require to make a new pack if you want to just have the inventory texture? Thanks in Advance if you actually do take your time to look after my problem 🫶
