writing out a new config file and doing a normal reload will accomplish the same thing and it's already done.  No need to reinvent the wheel, I don't think.  We manage the members of an upstream "dynamically" based on our CMDB, so when we add or remove servers, the changes are reflected in nginx and we did this without touching a line of nginx code.
