I guess if Spider-Man became Your Friendly Neighborhood Unstoppable Force, the player would have to spend the xp and give up his Web-Slinging. Am I right?
It depends on what you mean by "by the rules."
The "rules" allow you to change out datafiles when the Watcher allows. They also allow you to model datafiles to your heart's content.
So the rules would definitely allow a player (with Watcher permission) to create your Spider-Juggernaut! (I've got the issues where Peter was "Spider-Hulk!")
Now do the XP-spending rules allow for this? Without going to the book I don't know, and I don't have it with me.
