I have done Markham Heights from near the lookout.
As its only 500m, I rushed up there in a hurry without gaiters or any scrub protection.
It was scratchy, but didn't take long.
Certainly looked a lot more open from the direction of the Legges Tor track.

Good luck with that... Its going to be a pretty extraordinary dump that gets you all the way out there.
The valley heading out that way would be lucky to get enough snow, its just a bit low.
If you stick high on the ridge line over Coalmine and Magnet Crag all the way it might be possible.
I have memories of cross country skiing out to Coalmine - back in mid the 90's.
