What you suggest should work. The FTB website Military Spouses Residency Relief Act (MSRRA) (Click on link) says the following:
You may qualify for a California tax exemption under the MSRAA if all of the following apply:
- You’re not in the military
- You’re legally married to the military servicemember
- You live with your spouse/RDP
- Your military spouse must have permanent change of station (PCS) orders to California
- Your domicile is a state other than California
Thus, supplying the California FTB with proof of the above information (as you suggest in your question), should satisfy them. If necessary, contact the FTB to see what they will accept as proof of the information (you can access their phone number through the link I provided).
