Plenty of people seem to want options for more or less circle size, hp drain, accuracy, approach rate, or whatever. Why not have a plus and minus option (or range of options) for each difficulty stat? It'd let you enjoy playing harder or easier maps even if they're outside your comfort zone, or it'd let you train specific skills on familiar territory.
I like seeing my number go up and all, but actually improving and finding fun new beatmaps is more what I'm after; sometimes there's a cool beatmap, that just has a stat turned too far up or down that I can't work around it or it just saps the fun away. Of course balancing this on the leaderboard could be a nightmare, but it could be fully unranked and I think it'd still be useful and nice to have.
