So it wouldn't surprise me at all if suitable paper could be had. The matter of cutting it to the correct shape is a different issue, admittedly.
It may not be all that difficult. Perhaps the right method here is a die-cut, a common method for doing custom cuts of paper — often far more complicated than punch cards. The basic idea is that you build a form up with steel rules that define the edges you want cut. These rules essentially act as a blade. Then you mount this on a press, and run through a stack of paper as if you’re printing, but in fact you’re just cutting.
Here’s a basic overview:
A few years back, while photographing letterpress printers (see http://johnlabovitz.com/projects/letterpress), I met a fellow (Rob Barnes) in Denver who specializes in die-cutting. Like most die-cut operators, he uses mid-20th century Heidelberg letterpress printing presses. I have no idea if he’s interested in a retro-punch card project, but it might be worth contacting him.
Frankly, I think the harder task is to find a good stock of appropriate paper.
