If we're talking about creating an entirely new language, I don't think the "ideal" is Python with a few tweaks; it's going to be radically different. The point is, you have to draw the line somewhere, and if you're going to build an entirely new language, you should probably address as many problems as you can; few will switch to an incrementally better Python (unless you can give strong compatibility guarantees, in which case it's arguably not a new language).
