That’d definitely help when cutting large pieces, depending on where your cut needs to be you can end up with lots of material hanging in the air. If it matches the wood table then you’d have lots of options for stabilizing.
I like this idea, @iMakeRobots. The table saw pretty much lives on that wooden stand anyway, so it should just be fastened to it. The legs could then be cut down so that the overall height matches the other bench.
Up or down, my vote is for making sure all the work surfaces are at the same level, including the free standing horse stands.
and yes, +1 for bolting the table saw down. I did have an incident where the table saw almost fell off the stand while I was moving the whole thing around.
