You could completely abandon the existing design and go with something that works well in the CNC world for either the part or upper hotend cooling. http://www.loc-line.com They're usually quite noisy, though.
Why would you want that? Once aimed correctly it never needs adjusted?
I found them to work well in the CNC world. The stream of cold air is tighter rather than spread out. The flexibility is useful in the unlikely event that it bumps into something so it wouldn't necessarily break the part free from the bed upon collision.
The general advice though is that it's okay to break away from how everyone else is doing it and to reinvent.
But, you need to ask yourself, does it adds complexity and does it really improve the experience using the printer? It might do the second but at a cost of increasing complexity. Cost should be a secondary concern, with solutions nearing "Free" preferable over ones that require additional purchases.
That is one reason I never jump on the "Just buy Simplify3D" bandwagon. It costs. You can also duplicate most of the functionality in Slic3r and/or Cura. Just to be transparent, I use S3D.
There is a lot of room although constrained by other hardware for redoing the cooling. You could even repurpose the 30 cm part fan for cooling the cold zone. Almost zero cost except for time and a tiny amount of filament..
The re-purposing idea is probably the way to go. I just don't think I'd hold my breath for Robo 3D to cough up the file. I'd be more likely to just start from scratch and design a better one.
Yeah, I just don't want to take it apart again just to reverse engineer a part that they already have the model for. I am hoping maybe someone else would do that, but I might just break down and look at it this weekend.
I'll eventually start a design from scratch but it won't look much like the original.
Dan from Robo has promised to release the Fusion 360 file of the printable fan shroud. He did mod it to use three 30 mm fans instead of two 30 mm and a 25 mm.
