This is a reasonable way of doing things. Some providers do exactly this.

Beamr did an interesting review of the landscape and found several content adaptation methods

Beamr's tech is cool, they do frame by frame optimization in loop with encoding, so they calculate a lot of metrics for an encoded frame and then re-encode the frame with fewer and fewer bits until they get the lowest data rate possible while maintaining the metric score. It's more complex than that, but it's a tight integration. I've looked at their stuff and it's quite good. It's not cheap tho

Netflix does extensive content optimization (the per scene convex hull approach).
