Nice work! Thanks for showing it to us.
It seems somewhat reminescent of an older idea of adding a touch of feedback to a standard OTA shaper. I don't remember where I first saw that, but I was able to get it to work reasonably well, ie harmonics more than 40db down. Not bad, given that the Tri was derived from a Saw core!
