Frankly, I don't think so.
If you're familiar with RPL, you'll probably miss local variables.
Registers and variables are global, which can cause problems.
In general, I avoid alphanumeric variables and try to minimize the use of registers.

So we have a four-level stack, which can be challenging.
But we have LASTX and an automatic copy of T to Z and can use STO/RCL (including arithmetic) with all stack registers.

If you are familiar with Python, this RPN translator might be helpful.
The result can often be simplified, but it gives you a first approximation.

In general, the generated code for a stack-based VM (Java or Python) can be translated to RPN mostly verbatim.
If you like Lisp, you can try Clojure or Hy.

Now I wish you much pleasure in your endeavor.
