Suitless Vader's a nonfactor.
However, Vitiate can't take his opponents by himself. While stronger in the Force then this version of Sidious, he's not THAT much stronger. In fact, it's within the range of what Talzin, famous for amping people, can amp him to.
How big that amp is is interesting, though. On Dathomir, can she amp him to ROTJ levels? Even DE levels? More?

Actually, if Anakin were to let Vitiate possess him, that sheer raw power with Vitiate's knowledge and control...interesting fight. Presuming not, though, I'm not sure Vitiate's essence would have much bearing on this fight.
If that's what would give team 2 the best shot then yes, let's say Vitiate's essence assumes control of Vader's body. 😎
