Certainly - it might even be easier for tablet/mouse users. Regardless, I don't think this will be put into the game as an official mode as it can already (and only?) be done through mapping and if it existed as a game-mode - would most likely be unranked.
Peppy doesn't seem too big on the 'just cause' reasoning for anything.
Edit: I also beg the question of how this would be made algorithm-wise. The map you showed works because objects end and new ones start on the same beat, while normal maps have objects which end on different beats than others start. Ranked maps contain triplets, streams, stacked-repeat sliders and other elements which you simply couldn't convert to the sort of map you showed.
If you can figure out some algorithm for making these sort of maps automatically, I would be more than happy to make beatmap generator for these maps myself.
