You may want to take a look at my Vertico package which is on GNU ELPA.
It is basically a reimplementation of Icomplete with a classic dropdown.
The inner workings are similar to Icomplete. The main technical
difference is that Icomplete rotates the candidates, while Vertico keeps
an index. But besides that, Vertico is fully compliant with the
completion infrastructure.

Icomplete already should somehow work as a
`completion-in-region-function`, but I think it is a bit brittle.

Related to my Vertico package, I also have the Corfu package, which uses
a similar implementation as Vertico, but uses a child frame to display
the completion list (Similar to Company-Box, Company-Posframe etc).
