Excellent choices!
Only problem with that is that vanillas sell for the 1-2k price range.
Anything else could probably stay under your budget.
But to get something starting in your breeding project, I would recommend a pinstripe
you would make spinners with your spiders, lemon blasts with your pastels, jigsaws with your mojave, and maybe a ghost pin(never heard of it before) with your ghost, and just plain old pins with your normal!

I think the pin would do really good with your current collection.
