This wouldn't even be like a job for Ryan. Trading insults and giggling with Simon is how he passes his time anyway. If it comes down to a contract wrangle preventing Ryan from doing XF, then he should just do it for free!
Or if Simon wants to earn a few more dollars towards his next 'ex girlfriend' pay off, he could do a phone vote on who gets a place on the panel. I'm prepared to shell out for Ry.
