sure, put some clubman bars on it and pound some knee dents into the tank and you are good to go
However, if it was mine I would make it into a replica of what was club raced in the late 70's. The GT380's I remember on the track (not many) back then were lightly modified from stock. God tires, clip-ons, rearsets, chambers or a Strader 3-1, rearsets, good shocks, a cut down or replacement seat and good tires. Do the usual mechanicals like rebuild the forks, good tune-up and bearings and you will be good to go. Probably not cheap to do if you pay anybody to do any of the work, and not too bad if you shop for the parts and do the work yourself.
