I think that this algorithm must be implemented using shaders. Thus, FPS will be much better, and memory usage - less.

Not really. It wouldn't run each frame, just once when the sprites are loaded.

If you have more than 100 different skins you need to pre-render all of them into memory. With shaders you needn't ro do it.

This is simple shader, but unfortunately LOVE doesn't support shaders.

There's been a lot of talk about shaders, and vrld (who is a developer) has a fork which has them. I don't know what the status of them is though, I do they get included soon.

Very good

The difficulty with shaders is that we need to use some kind of shader language that isn't restricted to one drawing backend.

More importantly, one that is lovely.

Yeah, I'd love to code shaders in Lua with a lovely API, but I don't think that would be very speed efficient (double compilation).

Having a nice set of pre-compiled shaders seems the best option to me.

Meaning people can't make their own? If so:
