Unless the ship-based technerf plugin is re-written, it's not possible to make it usable on individual ships.
The removal of that plugin is why the BS scanner was usable on other ships to begin with. That was never supposed to last as long as it did.
I would like to find a solution that allows everyone to sink money into scanners that makes everybody happy including the Lane Hackers and I don't intend to rewrite the lore around it entirely, the problem is that the lore around it isn't really clearly defined anyway. The original Spyglass was, as I understand, an electronic warfare battleship that evolved into the current Arbiter.
Clearly that is not the same scanner as the current Spyglass that can be mounted on fighters, so I'm not sure what should be done with that.
