Seems like overkill - the interface would need more processor power than 
the ZX81, most likely.  There *must* be a company that makes membrane 
keyboards, and will do a shortish run.  I'd certainly donate a 
working-ish keyboard to get some made up...

As an aside, I believe a ZX Spectrum membrane is "close enough" if you 
extend one of the sockets so it reaches.
