Blend Modes for Curves?

I was wanting to blend two impulse curves, where the blend takes the larger value of either curve-A or curve-B -- depending on which is higher (kind of like the “lighten” blend mode for images). So far, I haven’t figured out a good way to do this with the present Curve Ops…

Likewise, maybe there is a use to have a “darken” blend mode (using the lower value between the two curves) when blending them? (And maybe even other potentially, useful image-blend-modes could be translated to the blend-curve component? ...But, actually, I haven't thought this out that far yet...)


Anyway, I’ve already moved on to other projects, but thought I'd mention it as something to possibly think about for future FF editions...
