Good idea for churn n burn?

I haven't had much experience with churn n burn and I figured since I have a bit of money saved up I'd invest it in a churn n burn site.
I have a money site setup with a good niche medium to high comp but tons of searches, 10 web 2.0's with 5 500 word articles of hand written content, and gsa ser with proxies and capatcha breaker. My plan is to continue to build the 2.0's to look natural and treat them as an actual website (like a microniche) then blast the 2.0's with gsa ser backlinks. Does this sound like a good plan? Can I improve it at all?
