merging mods for Bloodborne

[bullsh0ber]

Hello, I'm kinda new to modding, so please forgive me for the noob question.

I've been trying to run some mods on Bloodborne (on ShadPs4) by simply overriding the original files with the modded ones downloaded from here.
But I've soon run into issues with the fact that, for instance, many mods override the file /param/gameparam/gameparam.parambnd, so I can't have 2 or more of such mods working at the same time.

I've tried unpacking the gameparam file with Yabber from 2 different mods, and diffing through all the unpacked files (there's like 60 something of them), but there's usually thousands of changes that don't seem mergeable. My original belief was that every mod might diff in just few sectors of some of the unpacked files, but that's really not the case, there's changes basically everywhere across files.

I've asked Chatgpt but wasn't able to provide meaningful help beyond this, so I'm kindly asking you.

I don't know if this may help but here's the list of mods I would like to apply:
fps boost
fire torches
elden ring style prompts
more actions at lamps
change appearance
infinite ammo
weapon testing guy

And maybe as a side question: could patches applied from shadPs4 itself to the game affect the intended behavior of mods (like by 'overriding' some game files while the game is executing)?

Thanks in advance and have a great day
