Live Visualizer plus many other modules have ability to allow themes to be created.  It would be very awesome to have a collection created by other module owners that they either share for free or if very time intensive maybe a team put some work in on can be also sold.  This would probably help you build out a vendor part of Live Storefront collection as well to allow people to sell the customized Live themes at lets say store.mandeeps.com and your company could collect a commission from sales.  Allow free contributions and those that feel they deserve something for what they have created.  I feel it is all like art and work, some you just give away others are more timely special so you ask for a reward.  However it would be nice for all parties to understand that once it is purchased it can be used as many times as they wish and can use it as long as they have a valid license to run to module.
