seems to be an absence of far eastern fells in the OP which are some of the quietest fells
what about park at haweswater head and up the Rigg and then Rough Crag (amazing ridgeline with view of blea water) up to High st summit then round to Mardale ill bell, and either descend back to car park via Nan bield pass and small water or go up Harter feel and descend Gatescarth pass
or head other way from High st and go round high raise, law raise, kidsty pike way
or park near hardnott pass and approach Scafell from Slight side (for an out and back although can work in a loop I guess)
or eskdale, walk through Mitredale forest for an ascent of the Wastwater fells
or a walk around the forest and then Harter Fell (eskdale) in duddon valley
As an aside, I was going to go and walk the High stile ridge today but my dodgy knee led to me cancelling so sat at work.
