Alright then,
I'll ride it for now as is, and we'll see how the two of us get along. Mocking it up with the wheels I plan to use, rocking some Specialized Nimbus 700 x 38C tires, gives a standover height right at 34". That's pretty close to an "interference" fit, but the top tube is right in the correct ballpark for my liking.
Little more time with some acetone ought to clear out the last remaining bits of spray paint, then time to build a bike!

Thanks everyone for your input!

I'll keep this thread updated as things progress so if you're interested please stop back in.
