Bill Bremmers EBVT is already listed under the temperaments in Pianoscope in the Pro version (plus many others). I’ve used it a couple times and I just used the Hummel quasi-equal temperament yesterday for an antique piano with oval tuning pins from about 1830.

The only difference between the one in Pianoscope and the 1997 version is the D#.
You could add this new version by hitting the + and adding a new temperament.
