The Scarlet Witch could be a key character. Since she was central to the House of M event in the comics, her presence could add a lot of depth. Maybe she has some sort of connection to Spider - Man in this fanfiction, like she sees him as a key to either maintaining or breaking the false reality.
One idea could be that Spider - Man discovers a hidden power within the House of M world that allows him to break the false reality. He could start seeing glitches in the altered world order and use his wits and newfound power to set things right. Maybe he teams up with some other characters who also sense that something is wrong.
