(Question) True wakeword using custom OS/root?

[BURG3R5]

I wish for a true hands-free experience when using Dicio. As mentioned in #48 and here, "AlwaysOnHotwordDetector" is only accessible from system apps. Additionally, the notification tap necessary before any actual response is meh as far as UX goes. (Don't get me wrong: I'm really impressed by the work put into this project, and that is precisely why I'm interested in this question.)

So I was wondering if there's any way to modify the vanilla Android image so that it provides all the privileges that Dicio needs? I'm thinking of using Dicio on a secondary (read: less fancy) phone, so it doesn't matter if it the OS doesn't have X feature or Y app.

Is it technically possible to run Dicio with max permissions on some OS so that the UX is the same as Google Assistant/Siri/Bixby?

A modified OS could also solve issues like killing Dicio if run as a background service, etc.

I guess it is possible, e.g. if Dicio is a system app then there it can do anything I think, but I have no experience at all
