There is no insurance company that will insure you on doing that. Unless I don't know something - for which I would be glad to hear back that I am wrong.
Any travel insurance I have seen always excluded all kinds of sports which is also mountain climbing. They exclude everything that requires specialistic gear.
I also work in insurance industry as a software dev - nothing that I have seen would let insure someone who would go under-prepared. One could fill in form that he goes fully prepared but once lied insurance company won't pay anything.
Basically they will sell you insurance if you are fully prepared and basically you don't have any chance of claiming insurance.
