This is implemented in for example tabkey2-mode, but you always have
to type on TAB for indentation first. I think it would be too
confusing otherwise.

Tabkey2 has a list of completion functions and try to use the relevant
one. And let you change it just before you hit TAB again if you need
to.

See EmacsWiki for other alternatives.
