I also might combine the support plate with the ballscrew protection plate you suggested with a slot for the X-linear movement. That was a good idea. I dont know how the connection between the ballscrew and X-plate looks like yet. But it might work :)
I've got a slotted Y axis (you call it X I think?) It looks like this from the back...
