Yes, you are right. I started GL Jessica Cruz by pal-swapping Psylocke. Yolomate perfected the color and Gray Shooter added GL emblem (both are from MMV where it was there the first time I uploaded the palswap to). So, basically, it is more like an edited sprites rather than just a palswap now (I did more of her, actually, adding aura and editing some moves and changing some "aura" power so that she could resemble original GL Jessica Cruz more, but I lost all the progress due to HDD damage without having the chance to backed it up)
Back to topic, I don't think you need to add only the palswap version since it was only a "pilot" version to Gray's version.
