EDIT: Thanks to all the users in this thread like @Burgs, @Blix, @AlbertA, @Jesse, @Bakerman etc, who gave me tips and ideas to improve this further.
-------------------
I actually did a deep dive into ATs delays a while back when he was using the Timeline, and found "the trick" that I can't recall seeing anyone do in their AT presets (forgive me if I missed it). For some reason, I never shared the info, but better late than never right?
The Halo mode of the Keeley Halo is basically the same thing as what he was doing with his Timeline: 2 stereo delays in series, and each delay has the same times for left and right. One has the dotted eight on both sides, and the other has a quarter note on both sides. So they're essentially mono delays at this point (even though they are hard panned stereo delays).
So "mono", UNTIL: You introduce modulation. You can hear this in the official Keeley video for the Halo. As soon as they remove the modulation, the delays "collapse" to mono. Same thing happens on the Timeline. The modulation is different for left and right (LFO phase offset), and that's what makes it stereo and spreads it out. The phase of the quarter note is also inverted, for some reason. It actually does nothing for the stereo spread. Delay times are 360/480 ms. It uses a tilt EQ outside of the feedback loop, which is kind of unique. This means that the repeats don't degrade over time.
The only way to do it on the Axe-Fx, is with 2 stereo delays, plus a filter block. The dual delay type, quad delay variants etc, don't have the necessary architecture and signal flow to make this happen.
I used the clips from @Scented Meat Halo pedal as a reference (I hope it's ok?). First Halo, then Axe-Fx.
I've attached the preset below, which is just the factory Cliffs of Dover preset but with the Halo delay setup added. Feel free to lower the level of the delays, since they're quite high in the mix.
