You might enjoy doing the Lawyers ridge,
CS- 001 Ben Lawyers
CS - 004 Meall Garbh
CS - 026 Meall Creigh
I did those in 2022 in one rather long day lasting from 0830 and leaving leaving the 3rd top, Meall Greigh at 5pm. I didn’t arrive back at the car park until 9 pm. A pretty long day on the hill for me.
The only issue, problem or difficulty (depending on your scrambling talents) is the descent from Meal Garbh which was steep, loose and required the use of hands. I didn’t find it a problem and I was 72 so you should find it easy.
Just for info I was using HF and CW only. Someone else will tell you what the the VHF reception is like.
If you are interested my Activation report is at GM/CS-001, GM/CS-004 & GM/CS-026
