Well, the USRG10 has the string-thru-body bridge, and there are some older Musician models and the later US Master series guitars with neck through construction, but I can't think of one Ibanez guitar with both...
There was a setneck Ghostrider model with a tele-style string-thru-body bridge (GH320?), but it was only built for one year and there aren't many around. Lots of other setnecks with the tune-o-matic style bridge and tailpiece though...
The USRG10 might be worth your consideration since the unique PBC neck gives it tremendous sustain - much like a neck-through...
good luck
