[Closed] Pulling out internal runs advice needed - pic

Want to pull out this internal run on a Whyte M-109

It leads to the front mech and I have the stuff for 1x10.
Do I pull out the rubber grommets too and then black patch and add some copter tape over to seal the hole? I know it's an ideal dropper post route - but I don't want to run one.

Also to rerun the cable - I believe there to be no internal sleeve, so how do I get a cable back through, when I change my mind next week?

Only took me 3 hours to go tubless with Packing adhesive tape and valves! At one point it looked worse than the "badger" pic.
