I'm sure if an Eldar/Human scientist tried incredibly hard, they might just be able to create a gene-seed for xenos creatures (if they were genetically close to humans), but nobody really wants to, as 1) the Imperium doesn't want to give away its greatest asset and 2) other species don't have someone as smart as the Emperor to make it for them.
