Request: Extra images for reversed vehicles

Touching on this: https://forum.simutrans.com/index.php/topic,19639.msg192048.html#msg192048

In pak192.comic, some details are shown that make reversed operating trains look silly.
This includes the pantograph in use, front / brake lights as well as windscreen wipers etc...

It'd be nice to keep these awesome details in the game without confusing the player.
Thus I wish for a new imagetype that can be shown in case the operates reversed.

I can see that this may have benefits in some cases. It is not currently a development priority for me, as this would be non-trivial and I have a very large queue of higher priorities, but I should be happy to integrate this if anyone else were to want to implement this.
