This basically sounds like icomplete or Ivy, and might get the same 
pushback as the suggestion to use one of them by default.

In any case, I'd be happy to see experiments in that direction.

At the moment, IIUC, the UI either lets you cycle, or shows the 
*Completions* buffer, but not both at the same time.

Perhaps you're suggesting to remove that limitation (what would happen 
if I dismiss *Completions* and then press TAB again?).

Maybe the optimal UI which is close enough to the default behavior would 
look more like icomplete-vertical: the items closer to the prompt, and 
there is a visible selection which you can accept with RET.
