how about..

intermull / intermulli / intermullerian for intersex mullerians

interwolf / interwolffi / interwolffian for intersex wolffians

i added in intermulli / interwolffi because "intermull / interwolf" might be too short or ambiguous for some ( and "interwolf" could be used for a wolf-themed intersex flag edit, similar to edits archived on @intersexflags like Interstar at some point. )

if you wanted entirely different words and not just my ideas for combos ( like how i coined Absolnian for Anattractional and Anodiean for Anonbinary ) please feel free to send me another request for that !!
