I can only think of the M-Sport drivers and even there Armstrong was good in a Rally2 car. Who do you think would be overshadowed by WRC2 drivers?
One important notice about Vaher - he did only few races in 4WD machinery, but dont forget that he is part of Toyota programme and he did pleeenty of mileage during tests.

Sordo, paddon, pajari, katsuta, mcerlean. Maybe even evans and fourmaux.
