That's perfect! Notice the "scooped" out notch, that's exactly what we do to avoid the whole horizontal shear issue. If you run the calcs for square joist notches there's no way that would work on your longer spans, but the gradual transition works great.

But, if you add the midgirt like you show in teh picture it won't be an issue anyway, unless the floor load was very high because you're bringing in a tractor something.

Nice examples, thanks Jim (and Tim!)
