It's possible. Whis did seem extremely surprised by how far Goku had progressed.I believe that UI Sing Goku (Suppressed against Moro)> = UI Goku (ToP) because Gohan and the others just lost sight of the combat between Jiren and UI Goku, when the former went beyond the Limits. A much stronger Gohan couldn't follow UI Sing Goku (Suppressed against Moro).
