I'd love it if they released a something like a plastic model starter kit.
My dream box would be similar to what they already produce but a little more varied:
A plastic models kit with one sprue of the soldiers, one sprue of barberians, one sprue of Knights and a sprue of Wizards.
Another set could have a sprue of Cultists, the Gnolls, one of Skelletons and the same sprue of Wizards!
Mix and match! Make 2 whole Warbands!
One big detail the Wizards sprue should have at least 2 sexually ambiguous bodies and 4 female heads.
