This kinda fits into the threads not to make anymore...
You need coders, experienced ones, to make a project like this happen. And most of the time, even on open source, those coders are looking either for recognition, a project to display their talent to customers (this won't work for that), or one that will generate some income.
Even if you did it, EA will be on you like a chicken on a bug, unless you vastly revamp gameplay, terminology and operation.
At this point, I'd say go find the Thrive thread and see if you can contact someone there (there are links), or just wait for EA -- buggy or not.
