Have you considered using "Madoka" here in the renderosity freestuff? Madoka is an Animedoll/Aiko 3 hybrid with Animedoll's head (which doesn't have the eyelash problem) and Aiko3's body. Unfortunately, "Madoka" isn't flawless: her upper neck region is somewhat distorted where it joins with the head - you may need to hide this. Alternately, one can use Himeko, available here in the Renderosity marketplace. Himeko's bodyshape is very similar to Aiko's (she can fit in Aiko's clothes with some tweaking), and she doesn't have any eyelash problems. However her facial morphs are VERY limited.
