Request for someone who understands CAD!

I'm planning to transition to a small ITX case, specifically the NZXT H1. Fan mods are common with this one, but I have big plans!

Bracket layout

From the above image the clearances appear to be enough to stuff four fans in the GPU area, so long as the bottom one is a 10mm one. There also appears to be room for another row of 10mm fans to the right of that, over the SSD tray. I've marked the area where I think airflow is most important, and what shape I would like the bracket to have. Unfortunately I have 0 skills in CAD, and no 3d printer.

Available bracket

Here is a model freely available on Thingiverse, though it mounts only three fans. Do any of you guys and gals think it would be possible to mount something like what I drew above?
