I do hope Grandma is on board with the reorganization. In my family, someone tried to "help get Grandma organized" with my Gran when she was getting older and slowing down and after repeatedly asking her to stop and leave Gran finally leveled a pistol at her to chase her out and it caused a huge uproar in the family.
(Later we found out it was not loaded, but still. Gran sure had a way of getting her point across!) But she (the cousin) should have known better, our Gran was a firecracker from start to finish in her life and was not about to be pushed around by anybody, for any reason, even if it's just done out of love. (And I do think my cousin only had good intentions, she's just a little short on 'listening skills' sometimes.)
So hopefully this Grandma is not actually as reluctant as it sort of sounds she might be, and is not packing heat!
