I wonder what Spencer's plans for "sinless" Norman Osborn were. It was implied at the time that Peter allowing Norman's sins to be taken would lead to some kind of disastrous future.
It's hard for me to imagine Spencer having Peter or MJ ever play nice with Norman. MJ begrudgingly worked with him to stop Kindred but didn't buy into his conversion to the side of angels.
I can buy into the idea that Norman is at the moment sincere but I cannot buy that Peter or MJ would ever give Norman the time of day. Even if they believed him to be a completely different person than he once was, he's still wearing the face of the guy that killed Gwen Stacy and Peter and MJ's child.
