Sorry, I cant really answer you question, but Ive always wanted to see how nice a Workbench setup specifically designed around a high res non interlaced was possible if a person put some time and effort in. If a person looks at some of the hand pixelled icon/gadget/etc. graphics in old (320x200/256x16colors) amiga games then surely something pretty nice could be created in 720x283 (pal high res+overscan).
Ive seen plenty of nice looking ecs/aga setups before, but very few if any attempts at lower resolutons.
My semi-random thought for the day
