Probably, yes. But I still think it's doubtful he'd think he could access Vegeta's full power and not Goku's. He knows both are Saiyajins, and based on the example above it's possible the Saiyajins do share some body's traits. So for him to be sure he'd defeat Kuririn and Gohan with Vegeta's body, I think he might have been considering the likelihood of not accessing Vegeta's body full extent as well. Plus, like I mentioned, switching bodies with Vegeta was something he just entertained when he felt the weight behind Vegeta's blows and not upon seeing how Vegeta swiftly defeated a ~40,000 BP guy, so if it were simply a matter of Vegeta being a guy he can access the full extent of his power -- unlike Goku -- then possessing his body would have to be something he'd have already considered as a possibility.
