I know there have been several custom plates that work with the Pure. If you have one and are willing to sell it or trade for it, let me know. I have a bunch of things for trade, from custom USB cables to some water cooling parts and fans to wooden key cap pullers that I'm making.
Alternatively, I'm looking for a set of PCB mounted Cherry stabilizers. If you have any, let me know. I'd need a single space bar for a Pure and then three for the Shift, Enter, and Backspace.
