Not sure why you think it would leak more. With twice the thickness, it should seal much better assuming that the reason it's leaking in the first place is due to lack of a seal.
Twice the thickness is no problem. Using double stacked o-rings to do it is the problem. My background is BSChE with 23+ years in chemical plants. It will fail. You need a custom sized one that can withstand the heat and the oil. A nice custom made Kalrez one would be the ticket.
