We have no feats to say, but i personally think he can(at least theoritically).
Base Minato is already around V2 Raikage level of speed. Naruto who is much slower got a serious boost in speed when he got KCM, to the point he could match Raikage, so for someone who was already around Raikage's level of speed in base, in KCM, his speed would be crazy. With his S/T he can even redirect almost any attack(so Jinton for example could be redirected to the gokage). We've also seen that Minato is capable to warp multiple people in different locations where his markings are placed beforehand, and has shown to be capable to put his markings near areas like the sea, so the warping in volcano argument is definitely possible. If Minato places his seal near a volcano for example like he did near the sea in this chapter, and warp his enemys there, it's GG
That's what i suppose from what we've seen from him, but it's definitely possible now i think. I know many people would disagree with this though U_U
