Funny, I was looking at a '65 convertible 200 Saturday and was thinking the same thing! I think your idea is great.
I moved from Diboll a year ago, There's a diner called Ray's in Lufkin that does a cruise night every first Saturday of the month. Lots of Mopars - I was the only gen 2 Barracuda and there was an E body guy that showed up regular but the early Barracuda was well represented. I think I've seen as many as three at one time - very unusual! If you're ever having to get down that way, check it out.
