>He didn't have the nerve to lead the coup himself but wanted to be given the benefits after it was successful.<
If the coup you are talking about is Brumaire you are probably correct, but if you are thinking of 1804 I am not sure that there is evidence he was even expecting anything to happen.
>A secret royalist<
Do you know of any evidence that he was in contact with the royalists up to 1804.
>And finally he just wasn't in Napoleon's league.<
That is true of course, Napoleon's great strength was that he was the only one of the generals who actually wanted to be supreme ruler.
