No.

We don't see any reason to continue paying on one policy and buying another policy, in fact it is illegal to have 2 policies on the same insurable interest in some states.

If your insurance company can file the SR-22 for you, that would be the first course of action. If they cannot, then we recommned you find a policy that has an SR-22, purchase it and cancel your existing policy.

In addition, there is no such thing as SR22 supplemental insurance. An SR-22 is a state mandated requirement to show proof of coverage.
