Yes, I am concerned about modify-compile-test cycle. I don't mind length of
nightly rebuild and releases.

Do you mean that your project will be able to eliminate unnecessary
rebuilds? Can your code answer the question whether given object file will
change after rebuild without actually rebuilding it? Makefiles answer that
question wrongly in most cases and that's where the waste comes from.

If you already plan this, then I better wait for your results instead of
starting overlapping project. What do you think?
