I've had good success in the past with that same set-up. Your anubias should love it, the moneywort may grow. Mine grew like mad in a 20 long with the same WPG.
The thing with crypts (IME) is that if the roots are good, the plant can come back given the right conditions. I say this because it sounds like you want them. If this is the only place to get them, it may be worth it to check out the root systems of the ones they have and give one or two a try if they look okay. I've had some crypts that I thought must be zombies when they started growing again.
