Because the gear vendors cost around $2600 or so + rebuild back end of trans, and the 700R4 is FREE + $500 for adapter if I can make it work. I ask the question about the 200-4R to see if it would be even easier.
I was responding to the original poster, not you. You need to start your own thread with your question, or directly PM the person your asking a question to. Hijacking another persons thread causes confusion.
