I definitely lean more in the direction of Paul and Dairy as well, but if you are still looking for health insurance, then I can suggest Blue Cross and Blue Shield. With them, you can customize your policy to multiple adults and dependents. They originally set it up for small business owners to cover multiple employees and their families. Think of it as a group policy, but on a small scale. It doesnt matter to them what the relationship is, just as long as the premiums are paid.
I know that this was available in both Michigan and Florida, as the business I was associated with had the plans. The agent I met with told me it was their way of serving a market that hadnt been addressed before (ie small businesses, churches, common interest organizations, etc). One of his clients was a monastery, all adults, all covered by a single plan but individual policies. Another was a plan offered through a local credit union for its members and dependents.
With the advent of 'domestic partner' legislation, and the competitive world of health insurance, some companies are finding innovative ways of attracting new customers.
I can't help but think that an idealistic, aggressive agent looking to make a commission wouldnt find a way to build a plan that would work for you.
