That's not really going to help. For an MRI, you have to lay there being still, and for some you have to hold your breath, all while in a loud little tube. I have to get a couple every year, and I*m lucky not to find them too uncomfortable. Some folks, though, would have serious issues with the cage over your head when you get your brain scanned: Your brain and spinal column will take 45 minutes, as will other areas. You will need to be repositioned often, adding and removing things to get the pictures of all the areas.

In other words, you'll need an entire day off to do this if it is even possible for you to lay there for so long in one event, even if you get breaks. And for some folks it is going to be hours of torture.

More MRI machines won't solve the issue.
