Some sort of quality/resolution toggle

I have found that my game gets pretty good performance boosts on weaker computers by halving or quartering the resolution of my sprites.

So is there a good way to have a sort of high/low quality toggle for the player to swap between different versions of different sprites like that?

Would it work to set the different resolution versions of my sprites as different frames, and then when I want to swap between the resolutions I just swap between frames? Or would there still be a performance hit for just having the high res versions loaded in the other frame?

I'll do some tests and see if it works.
