Yes it's called stacking. Cliff has a mighty nice G90 stack.
Check out the screenshots thread.

I've done it with two Marquees. You can't do it with a lot of sets, some won't have the controls required to converge all areas of the screen. THis is especially true of a side by side stack, an over/under is usually easier to do.
Cliff's calibrator took 24 man hours to do a stunning stack,. 12 of those were on focus alone apparently. I've seen it, it was simply amazing.
I did it with 4 hours spent on two Marquee 9500s. Didn't come close to Cliff's when it came to focusing, but still, 2500 lumens out of a pair of CRTs was insane, everyone that came over and saw it was duly impressed.

What PJ's do you have?
You could stack top and bottom if you do not have two PJ's with the right geometry functions.
or you could do as i am doing(still a work in progress) and Blend ! one PJ does about 60% the other does the other 60% and the 20% is blended together.
PJ's locations

Here's my thread from a couple of years ago, stacking a couple of 12xx's I had at the time:
Sony 1271/1272 over/under stack... just for fun!
I really did it just for fun. I was well aware that 12xx machines were not good candidates for a stack, but I wanted to try it while I still had two similar machines to try it with.
