If Lex and Kryptonite are written into the sequel, this is indeed something I have an interest in seeing played out. Never really cared for how it was explained, or rather, 'not' explained in Superman: The Movie
, as Lex seems to be aware that Kryptonite is harmful to Superman almost by intuition alone.
