I appreciate all of the input and don't assume I know anything!! One scenario that is coming to mind as realistic is simply buying a nice, clean and popular 2t trials bike (so that the spare parts have good value) and swap in a KTM 125 or 200 motor, carb, seat, subframe, etc. Since I have both bikes currently and the KTM's wouldn't actually suffer any fabrication damage (cutting, welding, etc) it would be a fairly easy experiment. If it works, I'd have a nice 2t trials motor and rear section for sale, both of which should be fairly easy to sell for a fair price.
Keep 'em coming, I love the info.
