Skrillex -- I'd Need WAY MORE than Deadmau5 ... to Spin With Paris Hilton

Skrillex says he'd charge way more than $2 million bucks to spin alongside Paris Hilton -- but unlike Deadmau5 ... he's got a good cause on his mind.

Skrilly was heading into LAX to catch a flight when our photog told him about Deadmau5's steep price tag to squash his beef with Paris on stage.

The A-list DJ admitted he'd charge WAY MORE ... but you gotta hear his explanation for why -- it's actually commendable.
