In my years of experience, chromosome #'s are a guide, but hardly  a
given, as I've made many crosses, many of which should've NEVER been
fertile, and successful, but have taken, and produced seed.   Crocus
species which are supposedly incompatible have crossed.
One has nothing to lose by experimenting.   If you go by the book, you
lose.   Nature abhors rules, apparently.
I think curiosity and an adventurous mind will always drive a
hybridizer to achieve the unachievable.
