I'd pitch a crossover between DC and Dragon Ball, and feature the definitive Superman vs Goku event. Then I'd script out a logical, concise, completely realistic scenerio where two aliens fly around Morrison's "meta-verse", complete with cameo's from Arale, Lobo, Bobobo, and Mask trying to outtoon each other, Bibbo taking Zeno over his knee for misbehaving, and Toriyama-Bot and Grant Morrison avatar having a deep discussion about environmental shite as multiverses explode around them.

i think i would write about the adventures of galan the scientist/explorer in the universe prior to ours, before he became galactus. i would have a whole new universe to play with, could dry some cool parallels the series could eventually head towards the collapse of the universe.
also did some fan fic with an alternate version of sinister in the mid 1800's, and am working on finishing a western piece with phantom rider and black mask and a few others as they face off against varnae. i think there could be a niche for really well told western stories still. the era is ripe for story telling.
