I like the general idea, but I don't think it'd work. Rukia can freeze anything apparently, but I don't think she can freeze pure energy. Zanka no Tachi does not produce real fire - the reiatsu it covers Yamamoto (or Yhwach according to this scenario) merely takes on the form of flames. You can snuff out a flame by removing heat from the equation, but I don't think that's possible for reiatsu.
