I doubt you can do a 45 degree mount for the hoses. I'm sure the 4 mounts for the block are at the corners. So you could maybe turn it to the side but then the lines connections prob would hit the fan. Another turn and it would point straight down.
 
If the mount is separate plate from the pump then maybe you can turn it. I'd look for mounting videos of the hybrid block to see how its mounted.

It appears to just be a piece of flat metal with standoffs screwed to the cold plate side. Not sure if this is actually sealing anything, but just from looking at it from this video looks possible.
 
If you are going to attempt this, i would try removing the outter screws going thru the black plate rotating the bracket like desired first. Reinstall without shroud (and before cutting up shroud) to see if it works first. That way if it did'nt work, you could put it back to stock config and not void your warranty while testing to see if it even works.

Just rotate that plate without opening the block :) wouldn't want to loose the fluid.

Would love to see some after pics of the rotated lines back on the card..
