'A.I.' sources tell TMZ ... producers think Richie's legendary music career makes him a perfect pick ... credibility and a knack for honing in on what will become popular. Richie is also extremely outgoing, which makes for good TV.
TMZ doesn't know if the 'A.I.' folks have formally reached out to Richie. TMZ contacted Richie's people, but so far they're mum.
The question ... how much can producers afford to pay Richie, or for that matter any judge who fills the vacant seats? They paid a queen's ransom to Katy Perry -- $25 million -- which essentially blew their intended judge's budget.
As TMZ reported ... Ryan Seacrest is about to sign a deal to host the new version for somewhere between $10M and $15M.
