If you use Harmonic Pitch in Slot X (not in the "Stomps" slots) you can do a good emulation of the harmonized guitar lines during the solo.
If you use the Kemper Remote you can switch the Harmonizer effect on and off as the second harmony is only present during certain measures.
Maybe you can use some kind of dimensional doubling effect in another slot that stays on during the entire solo for that full double tracked guitar sound.
These settings are rough but sound pretty good. Just remember, the key is gonna be D (not G) for the correct intervals!
