Are interview type products good idea for WSO's?

Hi,

I have an idea for interview type of product creation as WSO's, but I'm not sure if this is a good idea, or even if this is allowed.

I'd like to create WSO's based on interviewing other "expert" warriors on different popular topics (like offline marketing, article marketing and SEO, etc), on live webinars, and sell attendance/recordings of the webinars, which are then sold to public as finished-polished products for 2-3 times the price at WSO's when all the interviews are complete, testimonials gathered, sales copy and graphics completed etc. I think that would be a good strategy for product creation from scratch.

Now, the rule with WSO's are, it has to be a product that I personally created. Is it OK that I interview 10 experts on a topic, is it considered as a product I created even if I'm not the expert, just the interviewer?

And, can I list a WSO even before the first interview is made? Therefore, I can build the list of attendees, survey them for their "burning questions" about the topic and share them with the "expert" in advance, so that the interview covers their questions... But that means, selling an interview in advance and asking for money for something that does not exist yet. Is it OK?

Can the other experts also promote the wso as their own product and wso, even it the product "collaborative", and they are not the sole creators?

Has anyone done anything like that before? I mean, there lots of interview/webinar type of products over the Internet for sure, but I could not even find a single WSO done that way before, and I'm browsing-searching WSO's for the last few weeks actively.

Is there a rule against that? Is it tried and proven to be a "bad idea" before -for some reason I cannot think of- ? Or is it just that everyone is too busy to test different IM methods themselves, and put up personal WSO's themselves, so no one does it that way?

Any feedback would be greatly appreciated.
