Yeah, this is what Steve Lukather does these days (since ditching his rack gear) with three Hardwire DL8s, one for the panning and two in series for the circular.
The circular is a good approximation. I run my TimeFactor mono into my H9, stereo out into a pair of Fender Princeton Reverbs spaced about 10 feet apart. Since there’s no diffuser, I use the Vintage Delay in both the TF and H9 with heavy bit crush and top-end roll off. With the amps spread out, it really does achieve a swirling effect which, after all, is the whole point.
A slightly more accurate method is to run the three delay lines in parallel to simulate the multi-tap. This requires a mixer on the back end (I use the good ol’ Rane SM26), however, you get better control of the panning and can also implement the -3 dB attenuation on the 292 ms (right) tap.
