I've never gotten the impression that it was the mechanics side of things that got to Simon. I think he was an engineer and inventor who was thrust into a CEO role and buckled under the pressures of running a company. If I remember right, he didn't use the embezzled money to take a trip to the Bahamas or buy himself a sports car. He used it to fund his own secret side-projects that he thought could save the company.
So no, I don't think he would or should ever start a munitions company or anything like that, but I think getting back to using his inventive mind productively could only be a positive outlet for him. He wouldn't have any of the pressures of running a company or the weight of investors and falling profits, which is really what troubled him in the past. It would be more like a hobby, no pressure at all, and it could help reinvigorate him without radically changing him.
