Good news and Good Luck!
At least you know what your doing and more realistically what you're up against.
The NCP'S will drive the C3M0280090D's just fine on 40m. However for a 1KW carrier your going to need more than 2!
For the crazy powers you are generating and the large gate C's (Qg's) the NCP'S will fry for sure driving high gate C FETs.
Sounds like you're best sticking with what you got!
