This is a really cool thread!
I'd take a quick glance at the desert ghost gene. Although it is a recessive gene and you said you'd like to wait on your recessive projects, it's doing some amazing things in combinations and there aren't a ton of desert ghost animals flying around either (that I am aware of).
Here are a few other animals that have come to mind that I think would be sweet!
1) Enchi fire: This combination is smoking hot on its own!
2) Disco YB: I personally like the disco over the vanilla because of the extreme ringers you get when combined with a fire. YB is, in my opinion, a must-have gene.
The first two females should produce super bright stuff that you'll need sunglasses to look at.
A hidden gene woma female would be cool if you like soul sucker combos. Another option would be to get a het platty daddy female from Ralph Davis for your pastel lesser boy. Finally, an orange dream girl could be another option.
By next year, you could potentially sneak a fair amount of these guys under the salary cap I think.
