Well, there certainly seems to be a healthy amount of interest in having traditional coloured Lemminas, so this will happen. I'll make them available as an optional spriteset, with instructions for how to implement them in a level/pack.
However, I'll likely use a different set as the official Lemminas II set, since I would like it to have its own look. D is looking promising, and it's a favourite of mine, but I do like the blondies as well...
It's a long way off yet anyway, so there's plenty of time to settle on something.
