I assume this is the session that produced the cover of "Tuesday's Gone" found on Garage, Inc.?

for sheer humor value, I'd love to see Dope.
more seriously, I think Flogging Molly could be good, and The Offspring might be interesting.

Marilyn Manson.

His covers rock I think it would sound errie as fuck over acoustic.

Weezer.

Their songs with "clean" guitar would sound pretty good I think on an acoustic.

Gnarls Barkley?

Venetian Snares. Unplugged.

hot fuck.

Yeah Gnarls Barkley could be pretty amazing with Questlove (hey he did it for Jay-Z) and a full chorus. Outkast would probably be great too. Buzzcocks maybe? they'd have to put their drummer behind a wall or he would overshadow the rest of them. I'd also love to see a lot of Prince's songs performed minimally. Or how about just Stevie Wonder and a grand piano?

Fiona Apple already pretty much plays unplugged all the time so I can't see that being anything special. Wouldn't mind if they'd show one of her regular concerts though.

I also wouldn't mind seeing someone like Ashley Simpson or Paris Hilton getting up there and being exposed as the talentless hacks they are.

Yes unplugged. i would love to see Roundabout performed in all acoustic.
