Fanfic Ideas Jostling around

I have all these ideas for crossover or fusion fics, when I know I should be working on my own original work.

Eclipse Phase: Crossover, The Mane Six find out their world is a hypercorp-run simulspace for the entertainment of Martian children. They are freed by Anarchists and sleeved in transhuman morphs. Now they have to figure out what to do next, do they side with one of the factions? Do they try to return to virtual Equestria or do they free their friends and family and recreate it in the real world.

Fading Suns: Crossover, the Empire finds Equestria, apparently a lost research colony performing genetic experiments on Shantor. The Mane Six are captured by slavers and sold to various Houses, Guilds, and Sects.
or Fusion, Ponies have an interstellar feudal Empire. The Mane Six are a group of nobles and their retinues seeking relics of the Second Republic.

Mindjammer: Crossover, The New Commonality of Humankind discovers a xenomorph colony on the Fringe, Equestria. The ponies must figure out if these strange missionaries from the stars are here to aid them or reduce them to slavery.
or Fusion, it's the Commonality of Ponykind. Twilight Sparkle is a SCI Force operative (and Spike's her Mindjammer) sent to the Fringe world of Ponyville to neutralize a budding culture conflict. She was encouraged to recruit locals but believes she can do it herself.

Sword of the Stars: Crossover, Equestria is a habitat station built by one of the older races to test out a species adept at terraforming. But they abandoned it centuries ago and now the station is falling into disrepair. The ponies must use the tech their progenitors left behind to colonize new worlds, however they find that they are not alone.
or Fusion, instead of Humans, Tarka, Liir, Hivers, Zuul, etc. you have Ponies, Griffons, Diamond Dogs, Changelings, Dragons...
