Can 2 different species do a dance fusion and work?
Simple answer is : it depends.

In the manga, it was stated that there are certain requirements to the Fusion Dance as opposed to the Potara Earring fusion, such as the mergers need to have equal power and roughly similar height, but in recent interview, Akira Toriyama said that it is possible to merge no matter the conditions, as long as it all goes well and it is even possible for a larger number of people to merge.
