Transformers In Passive Filters

So in a prior post (https://www.audiosciencereview.com/forum/index.php?threads/lattice-phase-equalizer.47694/) I wanted to use a lattice phase equalizer on every filter stage. I realize now that is dumb because of how many attenuator networks I would have to make. So I went back to the drawing board...

In the passive filter I'm working on, I wanted to account for phase as well as frequency. The only way to do that would be to analyze all 3 bands. How am I going to do that? Answer (maybe): reintegrate them.

Here's my question: could I use a transformer to reintegrate my low/band/high pass and turn said transformer into an all pass filter in order to analyze and, if need be, correct the phase relationship between the bands?

Did you lose a bet or something?

Maybe with years of work or something? What a very odd way to use a transformer.

Are you really, really, really sure you don't want to do things like that using DSP / software?
Please don't tempt me. I already had to talk myself out of making something with SigmaDSP lol

Nope! Just really bored and like to try stuff!

I have seen transformers used as outright inductors before in lots of different things before. Agreed on it being a weird way to use them, but nothing new. I also stumbled across something a little while ago talking about using an autotransformer as well.

Inductors, yes. It seems you need something like a phase delay network, which is quite another thing. Perhaps I'm not understanding.
