Keep the preorder and customise Kingdom Blaster into Marvel G1 Blaster. It's the only thing that makes sense.

In all seriousness though, Kingdom Blaster is great but it had lot of little inaccuracies in the colours. That's really the only thing SS86 improves upon but I'd say he's still worth the upgrade, though I am a little biased since Blaster is my favourite character and SS86 is my favourite toy.
