I think they should have focused on offering a single bundle that a large majority of collectors would be keen on. At the end of the project there were 87 backers for Desolataur and 60 Backers for Bloodbath. Perhaps set $120 for Bloodbath + Desolataur + a retro-print T-shirt (of either Bloodbath or Desolataur rather than the green alien logo - they've got cool art people want already so it should be pretty easy to pump them out en masse).

I don't think it's too far-fetched to offer two individual moulds in the same bundle as they've offered up Bloodbath at the same $55 price point.

Whilst the repaints/exclusives were nice, my first priority would be on completing these images:
