Anton Ertl has an interesting page here in which he compares the performance of a number of Forths on a collection of benchmarks.

http://www.complang.tuwien.ac.at/forth/performance.html

The relevant quote is below:

'These results also show that the following statement has not become outdated yet: ``The resulting machine code is a factor of two or three slower than the equivalent code written in machine language, due mainly to the use of the stack rather than registers.'' [Ros86]'

If I'm understanding this correctly, I think it is in support of your thought that MISC + registers may be a winning combination.
