Track Markers: Need advice on eyes. Ideal geo?

I’m trying to figure out these Track Markers for matching my custom geo to the MetaHuman geo. It’s a stylized bobblehead geo. Kind of like attached pic (but not ‘cause I can’t show the real thing) but same type of eyes. The stylized eyes come out horribly, the joints are in weird places, blinks like a folded taco. 1) Should the geo used for the Track Markers have the eyeballs as part of the head geo or as separate objects? 2) What do i do with the Iris Top curves ( if he does or does not have eyeballs? ) 3) metaHuman tries to replace the character eyes with it’s own undersized metahuman eyes… and it looks freaky like shrived grapes in empty sockets. 4) any other advice would be appreciated.
