With respect this is not a question for the Crewing Manager, maybe DFO or HR.
Duty of care is on the radar these days because of corporate manslaughter changes. The best suggestion you can make is that the flight (if possible) is crewed by LGW crews who position to LTN (either the night before or pre flight)
so they end up in LGW home base at 0745.
Some airlines do offer hotac but it's normally after long haul. Whilst you only live 12 miles away you have to be careful that you dont "screw" your colleagues who live further away than that contracted distance / time. Duty of care works both ways of course. Even if hotac is offered it's unlikely it would be booked until the day anyway. XX rooms = lots of money to be lost if things go wrong and you end up AOG in RHO. Then you get the usual crew discussion, if i don't use the room can i get an allowance which blows the discussion apart.
The simple answer is the rostering mentioned above
