Is it possible and would it be efficient to combine two projectors to increase the area coverage of the display?

I have a 4k projector from Sony. The problem is the maximum area coverage of the display is up to 300 inches. That is way too small for me because I have an available wall of about 50ft. It looks like consumer grade projectors have a display coverage area that only go up to 300 inches, however, Sony’s proline goes up to 1,000 ft. I can buy the sony proline, but it would set me back $150,000. The consumer grade projector only cost me $25,000. As a cheaper, yet possibly efficient alternative, I was thinking if it would be possible to buy another consumer grade 4k sony projector and combine it with the one I already own which would theoretically double the coverage area of the display from 300 inches to 600 inches.

Would that be possible and more importantly would the quality of the image be just as good? It is mainly for movie viewing.
