I think that POS should be converted to Mobile Depots to enhance the Mobile Depot play functionality.
Mobile Depots are great because you deploy them and then use their fitting service and cargo storage for what ever you need.
A Large Mobile Depot would allow a player to anchor the depot to a planetary object such as a planet, moon, mining belt, etc. too have a base that they can dock up in over night and continue to adventure from the next day. Basically like a tent that an adventurer would use in D & D.
The Explorers Depot would have the following capabilities:
Cap charging, Shield and Armor Repair but no Hull repair
Cargo Bay - 50,000 m3
Fleet Hangar - 400,000 m3 (up to at least three fully rigged Navy Ospreys)
Mobile Scan inhibitor Array that turns itself off for ten minutes when a ship tethers to it for repairs otherwise the Mobile Scan Inhibitor would prevent the normal operation of directional scanners and probes within its 20km radius. Any objects within range of the Mobile Scan Inhibitor will not be visible to these sensors and any ship within the radius will also find their own instruments rendered inoperable.
Due to the immense power consumption of the Mobile Scan Inhibitor Array the Explorers Depot un-anchors itself after three days of use and would need to be re-anchored in order to use again. When un-anchored all ships and items are jettisoned into space.
The Explorers Depot might seem too large to haul around but due to advancements in sub-Quantum engineering as a result of Drifter, Sleeper and Triglavian technology, scientists in New Eden have been able to fold the molecular structure of the components that make up the Explorers Depot over on themselves similar to how a folding beach chair functions.
In the video below each molecular structure layer of the depot is folded compactly and then opens into the depot.
