OK.  I KNOW I know this, but I’m coming up with bupkiss so…  If I wanted to do a double headed charge (similar to the double headed eagle) using two different animal’s heads… how would I blazon that?  Just the heads are the charge, not using whole bodies.

Probably "the heads of an x and y conjoined on one neck". Not too sure how well it would work though.

dimidated at the neck??

do they have to be drawn as conjoined?  could you get away with "the heads of X and Y couped and adorsed"?

Thinking of something like this (looks like a black cat and an eagle) but I don’t know the blazon.
