Is this a question of individuals or as a whole? Like, can YX33A pass K1 or can anyone pass K1?
If as a whole, K5 is possible. Consumption of such power and storage aside, one could "easily" generate such power.
Your back of the envelope equation would indicate this @malicious_bloke and if extended, one could calculate how many it would take to reach K2, then K3, K4, and K5.
If one wanted to say just having power generation on such as scale isn't enough, well, a few RF Tools mining dimensions could justify such power generation, a few von neuman CC or OC robots would justify such resource intake, and a few ElC Aurora Batteries may store enough power to fuel those von neuman systems.
