While I would certainly not object I am not sure how useful they will be -- things have changed quite a bit in repro land these last couple of years. It is no longer a rebadged 3 in 1, grey copies of pokemon or thing with different sized pins to stock but the sort of thing you have to open up to see.
Sometimes you could shine a light up inside it and see, other times the silkscreening will be good but the wrong numbers for the age of the game. You still have the older ones, and ones people care less about (wrong colour cart, still using a flash cart, wrong colour PCB, bad label prints...) but it is pretty much PCB shots or nothing these days.
