I've been a happy HHKB user for almost 10 years and a Vim user slightly longer, and this is exactly what I do (though ctrl is already in the right place on the HHKB). I believe it was one of the first things I figured out in Vim, because it was so annoying to me to have to go all the way up to the escape key all the time. Ctrl+[ is such a pleasant little chord to hit.
