- bulbs tend to develop a green 'cast' during the 2nd half of there 'expected lifetime' and often at different rates which would be somewhat noticeable in a multi projector setup.
I would budget to replace at 1500-2000 hrs as a set of bulbs of matched manufacturer/batch (maybe 2-3000 hrs in eco mode)

Lens offset- the projector you list has quite a high offset which may cause some problems in setup in portrait mode. I'm sure you have the physical side worked out to get a 'virtual point of projection' but i'd be slightly concerned at getting a perfect match up with the most 'distorted edge (the normal 'top') being next to the least distorted ('bottom') of the next projector.
This is a 'theoretical' problem and you should be able to compensate with keystoneing - but it is something that would nag at me if i was spending 5k and i would certainly look for other options with less lens offset if going portrait mode if possible.

That's my thoughts anyway, be very interested to see how it goes

Thanks for your input!
I have considered the issue of lamp life and keystone issues which is why I want to go with probably LED based 300 to 500Lumens projectors (probably this one the vivitek qumi q2 led projectors only $500ea) which would be mounted at the back in the centre point of each screen position to avoid keystone issues. They have been reviewed to have a good image quality beyond what should be possible for a projector in this category! PS. the edge blending software or hardware would fix the offset problems.

id basically go from this below....

and end up with something looking like this.. (the opaque white overlay)
This is from my original build before the baby took over my office!
