A NanoStore upgrade for most of the classic older Yalms would be awesome. Sell an item that tradeskills with a classic Yalm and makes it a nano formula like the current Phasefront/Yalmaha Clio.
There is a bunch of cool older Yalms like the Stiletto but no one uses them anymore, even without the Veh Air requirements they still have a long cast time compared to the new ones.
