It's not a stupid idea but I wouldn't really think of it as being Forth.
It's basically how Lisp, Python, Ruby, and maybe 8th and Oforth work.

I'd say get the simple implementation working before worrying about
optimization.  If you do the simplest possible thing there will be a big
slowdown compared to traditional Forth, but it will still be fast enough
to be useful.
