I'll just say that there is some question as to whether the entire premium would be taxable, or whether just normal taxable term costs would apply. Or maybe I'm misunderstanding what Bill is saying in his post.
I'd be more concerned with establishing a PS plan, and funding it with just rollover money to purchase life insurance. Unless you have other, "recurring and substantial" contributions, then I think you have a potential qualification problem.
Thankfully, we have almost no plans that even permit life insurance, much less actually purchase it, which helps me to sleep at night.
