Sure thing.
I can slot them, but it won't be very neat. I would just keep them to be honest.
When travelling just undo rear mech, put in bag and tape to frame. That's what I do. If you want to remove completely I need to slot or change all cable guides.
Yes as it clears fine to leave, but if possible could you slot the bottom cable stop?
Also, don’t worry about the mid fork eyelets - I found a cheap canti mount front rack.
