Does anyone know how easy/difficult it is to add these mods to Fallout: New Vegas on steam Deck?

Required for most mods:

XNSE

KEYWORDS

JIP LN NVSE

SHOWOFF NVSE

JOHNNYGUITAR NVSE

VANILLA ANIMATION WEAPONS SCALE FIX

IMPROVE CONSOLE

IstewieAI TWEAKS AND FIXES

YUP

The mods I actually want:

Classic Weapons

Hitman pickups (B42 interact, key item pickup & skinning animations)

Titans of the New West

Im probably going to add cowboy weapons and New millennium after I buy all dlc (I bought standard) but I really want to know how difficult it is to add all the "Required Mods" first
