For example, some players might find that they like the smaller circles that HR provides, but the higher AR and OD makes it too difficult for them to play with it

But seriously, you can achieve something like that in the editor.
This would make it so you get x1.02 multiplier by making most maps easier (higher AR). Also the difference in Circle Size is not noticeable in most maps.
I sincerely doubt this'll happen. If you want customization, there's talk about making Easy mod customizable at the cost of a score penalty (much more balanced.) t/56606
