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.
I got a bit more done during my lunch break.
It looks like the cable will clear the new canti studs just fine, so if you don't mind I will just keep them where they are.
So basically I am just a couple of M5 bosses away from being done.
