Mathematically not possible. Stochastic also depends on the High and Low prices, and not just on the Close price. So it can't be applied to other indicators.
EDIT: Knowledge is power, so my advice is that you always study the mathematics behind any indicator. It will help you understand how it works and how best to apply it in your trading. Don't just take that knowledge for granted.
You will have to search for it, code it, or hire someone.
Look at the stochastic(close) and incorporate that code into stochastic(rsi)
"The Stochastic RSI indicator (Stoch RSI) is essentially an indicator of an indicator."
