Would it be feasible to cut a couple of key blanks out of metal plate? Maybe metal strips?

Entirely feasible, and expensive. I had only been following this thread casually, but I think you have the necessary information in hand. (I'm gonna go back and reread the thread; now I'm reeled in)
You need precise (to your spec of precise - I don't know how much "slop" is too much for a key) measurements of the overall thickness and width, length, and the depth and width of each groove.
I'm inferring that you're not certain whether one key performs all functions or several keys with different groove patterns will be needed. If I were setting up for the latter, I would want all possible configurations in hand before starting. Fixturing and securing the raw material is a big part of the expense, so I would want the fixtures - jigs - to allow for all needed patterns.
I have the software and the machinery needed to do this, and if I were on your side of the water I'd love to be involved, at no cost. It's a really interesting task.
