A rough sketch of the plate. I used another pair of cycling shoes with SPD cleats mounted to estimate the cleat hole placement since these plates will not allow for adjustment. But since I know my own needs I can dial the hole placement in the plate to the correct place. If I measured or estimated wrong then I will have to make another plate which shouldn't be all that hard. Just a little more work.

The rest of the project should be small petty cash items and the inner shoes will be the primary cost of the project. The next few days I will cad out the sketch and print an accurate pattern on the printer to make the part out of. Then I can place the paper pattern on the shoe first to see if my design is good. If anyone has any good ideas for a heat barrier gasket that will be cheap and easy to find I am open to suggestions.

I think some ultra high density closed cell foam might do the ticket. Like the stuff padding my calipers in the it's case.
