Depends. On the Invisible Hand his blasts are significantly less dangerous than on Ambria because of the lack of dark side energies to fuel them with. Bane, on the other hand, possesses very powerful lightning which Kun obviously could evade, but it still might trouble him. Both have displayed Drain, but there were circumstances to this; Kun did it when surrounded by the dark energies coming from the Massassi temple, while Bane amplified his own power with the help of a Andeddu's temple. Bane is more powerful telekinetically, though. His raw power is greater than anything Kun has ever shown, and if he gets the opportunity to unleash a Force wave, then it could potentially prove fatal for Kun. On Ambria, Kun would likely win due to the immense power that the amulets have shown when enhanced by nexus powers.
I think you're giving far too much credit to the nexus with regards to Kun's amulet blasts. I already argued with scans that the blasts concentrate Kun's own rage and manifest as the blasts. At no point are they indicated as drawing on the nexus.
