That's an interesting idea. I've seen your package before, but didn't 
read through the whole thread.

Vertico follows the design where you put less importance on the 
prefix/TAB completion but instead excepts the user to enter more text 
for narrowing, which works well with the orderless completion style.
But note that Vertico is fully compatible with default completion, so as 
you observed you can just use `minibuffer-complete`. If you bind 
`minibuffer-complete` to the `vertico-map` it will work. See 
https://github.com/minad/vertico#keymap.
Is that good enough or do you have something else in mind?

Yes, I've also observed issues with minibuffer messages appearing at the 
wrong place. Vertico uses overlays to display the candidate count and 
the candidate list, similar to Icomplete. Icomplete however removes the 
overlay in the pre-command-hook and puts the overlay back in the 
post-command-hook. I am not doing that. I just move the overlay to the 
end but it seems this solution is not good enough. Since I have not yet 
understood fully what the problem is I haven't done anything yet to fix 
the issue.
Besides, my recommendation would be to deactivate those messages. I 
think they are pretty annoying. I suspect even more so in combination 
with aggressive-completion.
(advice-add #'vertico--setup :after
            (lambda (&rest _)
              (setq-local completion-auto-help nil
                          completion-show-inline-help nil)))

Thank you!
