I would say that this should be possible. I don't have any direct experience with it myself, but I have heard of people setting up many monitors with synchronized views across each one, so I'd think you could do the same thing with projectors.

I make no promises though! 

THere is also some software out there that allows you to bend / blend the edges of images to make them more seamless or to use curved screens.  If I remember correctly it costs something like $300 a pop or so... but if you are going with that mcuh expensive hardware anyway.... hey..... what's a few hundred bucks?   

best,

PS:  Yes it can be done.
