Good. I was thinking about something similar, but your details are more developed. In Python3 there is something vaguely similar, named bytearray.
(Eventually I may like a Dstring-like struct that contains compressed dchars and allows for random access with [] with complexity O(ln n). The compression allows to reduce cache misses and reduces memory traffic, improving performance in some special situations. But this type is for later).
