I have no experience with the XSW-D, but check the specs more carefully.
It appears targetted specifically at the camera market, with a rechargeable Rx which has 3.5mm jack output.
From the sound of it, you do want the rechargeable Rx. But be aware that it's another battery to monitor and ensure is charged for every show, which may or not work for you. If you want it powered, you'll need to leave the USB charger plugged in.
The 3.5mm TRS output may bite. There doesn't seem to be any spec for it, but I'd expect it to be a stereo 3.5mm plug if it's connecting into cameras, presumably running as a dual mono configuration. Assuming you're plugging into a conventional XLR mic input, you'll need a 3.5mm TRS-> XLRM adapter lead. Don't fall into the trap of getting a balanced TRS -> balanced XLRM adapter, though, as that'll bite you. You need an adapter that takes one side of the TRS to an unbalanced XLRM.
All this could work, but I'd be going for a conventional wireless system. It'll add reliability, as the Rx won't run out of charge mid-show. And, if you buy a system that shows the Tx battery level on the Rx, you'll add even more reliability.
You don't mention what other kit you're using, but why not case the Rx in with it? Racks and Cases are a burdensome cost, but protect your kit, give you fewer boxes to carry, and can reduce the cabling burden by leaving some kit permanently cabled.
