Half-Elf to be able to disguise as Elf races
Half-Elf to have access to Elf Head Models

A half elf has plenty in common enough to pull this off disguised. A tall Sun Elf can disguise as drow, but a short half elf cannot.
Physically makes no sense currently. Half elves are described closer in looks to Elves half of the time. Pointy ears and all. It would make total sense to have this option.

Did a height check before this suggestion. Half Elves can look eye to eye with tall drow. But a tall one would look a bit out of place. Not nearly as tall as some other elves.

I think this would add more diversity to disguises and open more channels of RP between the races.

Half elves and elves are not the same creatures. Using the same headsets doesn't work either, as they're different sizes. Rejected, at least for now.
