Might fit better as a mod, but I figured I might mention it here first:
Some system (probably an add-on equipment?) to allow a VERY EXPENSIVE XASER request while on a dive. The request would be placed, there can be a timer of some kind waiting for approval, and if approved, monies are transferred to E' and a path 'OUT' is cleared via XASER.
Smallish chance that the request is denied naturally. Request denial if there are other vessels in the area. Etc
Not sure WHY this would need to be a thing, because we already come FULL STOP (0 dV(r)) to astrogate back to E'. Thought it was a neat idea. 😄
