Chalk, as such a big Sheridan fan, I recommend that you pick up a copy of Osprey's title on the subject. There is some stuff in there also on the various vehicles intended to replace the Sheridan (none of which actually "made it").
I've thumbed through it a couple of times at the local bookstore and it looks pretty cool.

Amazon has it too. And no, I don't work for Osprey. Wish I did, sometimes!
I like your idea, BTW.
Anyone know if the U.S. has any other older AFVs sitting around (c. '97 or before) in decent enough conidition to return to active service (probably in the CONUS only, but who knows) either as-is or modified in like fashion? I'm thinking of M60s, M48s, Cadilac Gage armored cars.
