The fact that he won't get siphoned off by a cabinet appointment is the only downside to Biden not taking office.

Maybe we can get Trump to appoint him vice climate czar or something, and then send him to Antarctica where he can provide daily onsite reports about the state of the ice sheet.

I'll volunteer to be his communication liaison. Call him up once a day and ask him he's still freezing his (metaphorical, of course) balls off down there.
