How to know which chalices can grow into each other

[ducati335i]

There is a totm in which some chalices grow into each other.. They have smaller mouths... Seems like Miami hurricane and mummy can grow into each other.. Then the bigger mouth ones should be able to grow into each other or? I have a large collection of chalices..
They are getting addicting... The more you have them, the more they develop insane colors!

Well I think they have to be the same kind.. I know my hurricane and mummy will do but who knows about the bigger ones!
