How does making Xien being the wolf equivalent of Gurid sound?
Or maybe a werewolf?
Or maybe a werewolf?

Those 2 units have been removed from the game, so anything that refers to them in a Module is a big no-no.
But it does make sense that the only conflict would be those 2 references. They should be rather easily removed, but there might be further conflicts which are not so easily fixed.
I'm not 100% sure on this, but I think if you do a find-replace in the XML changing UNIT_ACROBAT to UNIT_HUNTER and UNIT_SECT_OF_FLIES to UNIT_CHAMPION you should clear it up.'Tag: UNIT_ACROBAT in Info class was incorrect.
Current XML file is: modules\can directly build arcane units\civilizations\tweak_civ4civilizationinfos.xml'
The second is:
'Tag: UNIT_SECT_OF_FLIES in info class was incorrect.' Second line is identical.
