A Cullen's life

So i was thinking

So I was thinking I do another book with Sarah's kids life or I make a twilight crossover with the originals.

Or I make another book but the oc is with Emmett and rose.

Or Edward and Bella.

Or Carlisle and Esme.

Or Alice and jasper

Or the oc gets with renesmee.

I was also thinking of doing an Disney descendants book.

I also thought of one with the whole pack or the whole Cullen family but then again I don't know it depends on my mood.
