Sell the fancy shock and bags, get all your money back.
Then you can decide to:
1) Part out the rest
2) Do a functional, non-cosmetic, fix and flip (with a cheap, used shock). Somebody will always need a reliable beater-bike to use as a commuter.
3) Lose a lot of time and money trying to sell a custom build
For me, it would come down to 1 or 2 above. If you intended to keep the bike, it might be a different story, because then you'd be building something that you'd want to ride.
I'd lean toward #1 - if you can get about $1,000 out of the most desirable bits, you can scrap the rest and only have invested a few days. Or keep the parts and find another bike that needs some of what you retained.
