I'm sorry it took me so long, and I'm sorry I've got your hopes up only for them to be dashed again. Y'see, I completely forgot about here, and I have no ideas myself. I've dumped these stories on my friend LovinaHolmes, and as she's a great writer, I'm sure you'll love what she does with them. She's free to do anything. I hope you guys can travel over to her profile and read her continuations/rewrites/whatevers of Thunderstruck, and the Mismatched Mutants.
Again, my apologies.
