I'm creating a race in the CK following the tutorial here: http://wiki.tesnexus.com/index.php/Creating_a_custom_race_for_Skyrim

I'm at the point where I need to create the Head Parts for the race. I'd like to have the race use the available hairstyles/hairlines/brows/eyes available from several races (Human races eg Imperial and Nord) but creating new forms for every hairstyle/hairline/brow/eye I'd like the race to use seems tedious.

I'm aware of the HeadPartsHumanandVampire form list. But my concern is adding the race to that form list a dirty edit? Will it conflict with other race mods if someone else decides to add their race to that form list? Or will both races simply add themselves to the list and not conflict with each other?

If the above is possible it seems like the most flexible way since custom hairstyles and such should become available to that race when they're installed without any .esp dependencies yes?

Thanks for the help.
