How about this
Preview pic from Weyland-Yutani's most recent Off-World Defence brochure. The girl in the photo is a human/alien hybrid, where the genetic traits of the egg pods (the normal birth method for face huggers) is genetically engineered into a human vagina, allowing for these female hybrids to give birth to multiple face hugger offspring in a far shorter time frame than the classic egg pods do.
The engorged clitoris has a purpose, it allows the immature face huggers to suckle on something just after birth, to give them positive reinforcement of sucking on enemies faces. However, to avoid unneccesary damage to the host, the face huggers are quickly injected with a strong barbiturate solution which renders them docile enough to be quickly relocated to holding cages, before deployment in off world combat zones.
Unfortunately the sever trauma of the births themselves destroy the mutated vaginal walls very quickly, so the hybrid hosts tend to be torn apart within 50-120 face hugger births.
However the Weyland-Yutani corporation is researching novel new methods to increase the cellular strength of the hybrid's vaginal walls and labia, which include strong synthetic polymer webbing to support the already strained uterus and vagina. The second generation of hybrid hosts are close to deployment, and will guarantee Weyland-Yutani shares to rally hard in the near future.
