g65 is a great motor, but the HazMat fee drives me nuts. Be aware it's a moon burner, so it will almost certainly spiral under thrust due to the substantially off-center propellant mass.

With that in mind I would absolutely recommend reinforcement. Either of the two methods you mention should work fine.

Make sure you have enough delay grain, also.
