I don't think there are enough cars to ever support any type of competition. When you take the evolution of the cars and owners that are willing to race their cars into consideration it would be tough to put any type of Racing format into place. You would need at least 3 of each generation Pro Stock. You can't race the first generation cars which were basicly Super Stock cars with tunnel rams against tube chassis cars. I just don't ever see it happening. The NSS classes could evolve and include a NPS and start off with a 1st generation class possibly 3300 lbs. 440 ci limit no dry sumps, must run tunnel ram and manual transmission, period correct hood scoop,latter bar suspension and 10.5x30" tire. Headsup no index. That would make for an exciting fun class.
