I have tried it in the past --- Haddoni with an LTA (( M doreensis )), and then a Haddoni with an BTA (( E. quadricolor )), and both cases the Haddoni was moving a lot and wouldn't settle in (( same with the LTA )), but once the other anemone species was removed it settled in --- nothing else about the tank changed. So, I am not a fan of mixing species of anemones, color morphs of the same species have been fine.
Plus, given the size of your tank, really would only be able to fit one hosting anemone anyways.
