Large scale Silverliner or similar models (other than Aristo RDC)?

A little off the topic of kitbashing, but will you be attending the Great Train Expo in Reading on Saturday this weekend?

looks like you best bet is going to be finding an Aristo Budliner, LGBs new Amfleet cars will  be too new, but the older Heritage cars might be kitbashed into an Electric MU.

I'm looking for models of something like the Silverliners that run on the SEPTA regional rail line that runs a few yards from where I'm planning on putting my layout in.  (For details on the cars I mean, see the Wikipedia SEPTA entry under "Fleet:Regional Rail Trains").

The closest I've found so far is Aristo's Budd Rail Diesel Car, which I found on the Aristo web site.  It looks a lot like the converted Pennsy Budd Silverliner IIs that run on some of the lines, but with different windows, a different roof and obviously without the catenary masts.  However, the RDC isn't in the latest Aristo print catalog and I can't find it for sale anywhere (even eBay), so I'm assuming it's out of production and I'm not going to be able to find an undecorated one to Septa up.

Does anyone else know of a similar product from another manufacturer--something self-propelled, silver, ideally blank or with Pennsy livery, in a similar design?  My only other thought would be to try to fit a motor into the USA Trains Amtrak aluminum coach, but I don't know how practical that is (I haven't done any G-scale kitbashing or opened up a G-scale loco yet).

Has anyone else tried something like this?
