Looks GREAT to me!

My plan is to have a main "mother" module where you can select which processor you want to hear from a dropdown menu. The output will then be audible and only that selected processor will be visible and use CPU. The dropdown menu will list a very brief description.
In this way you would be able to compare any processors A/B in real time using the current audio input.
The mother module will have level meters, balance and volume controls and an overall bypass switch. The whole thing will be DAW compatible but won't have front panel presets since each processor will be simple.

I'm still experimenting with the processors of course.

Cheers

Ou ...! I realized then I should make 3 buttons, two small and one large (main) ...
The screen I wanted to use for the phase analyzer ... can I? :?:

I considered using a phase analyser on the mother module since it only needs one for the whole project, so yes, but not one per processor!

This one is the simplest mono to pseudo-stereo system first proposed and created by H Lauridsen in 1954.

I may develop this further since the original design used a speaker with no baffle, placed at 90 degrees to the mono delayed speaker. This produced a non-delayed antiphase signal and a small air-based acoustic comb filtering effect but relied on room acoustics for colouration and reflection.
Also a speaker with no baffle has very limited bass response so that's a further clue for the simulation.

Watch this space... :D

Here is the enhanced Lauridsen mono to pseudo-stereo processor.

I've added HPFs to simulate a baffle-less speaker and a bit of variable ambience (reflections). Quite interesting results on a mono signal...
