DA challenge

So I have this idea that I can't get out of my head and I'm not the greatest writer so I'm putting it out there for anyone that's interested in using it.

Some Harry Potter characters, mostly DA and family/friends are caught in a ritual/spell backfire and end up reborn in LOTRs and the Hobbit world where they all end as slaves in either Moria or Goblin Town. They band together to escape and end up either overthrowing there captors and taking over the place or escape and become a sort of tribe the goes around freeing other slaves and killing orcs.

Some ideas:

The HP characters can be spread through the races, so some are dwarfs, some are elves, some hobbits, some man, others skinchangers.

Weasleys siblings can be a dwarf family

Harry can be a girl

Can happen in any timeline

Kili or an other character can be another slave

They can show unity by keeping one cuff as a bracelet but engrave with symbol that means some thing

Can have a song they sing like I'm still Standing

These are just some of my ideas nothing needs to be used if anyone is interested.

I don't respond to IMs so leave a review if there is any questions.
