This isn't helping but in the introductory plasma physics class I took in grad school (which I kinda liked) the hand-waving worked like this: You use Maxwell's equations in their regular form, don't worry about relativistic effects because all the particles we encounter in our MHD are "slow" and you'll usually get to look at your results at the end and say which terms you can drop because they're not significant. If and when your plasma flows get into the realm where relativistic effects would matter, you're probably in the accretion disk around a black hole or some such environment and puny Lorentz transforms won't help you and you'd need a full GR treatment anyways. 🤷‍♂️
