Custom sized radiator for FMIC in SMIC position

Ok, so I got this crazy idea. I get those a lot "lol". Instead of converting my Apexi FMIC in to a v-mount I can have a custom sized radiator made in the same rectangular width and height as my Apexi FMIC. So it will be mounted similar to the M2/ASP large SMIC location. This allows me to create a box style duct all around both. As we know ducting is the key to better cooling. I have contacted Koyo about a thicker and/or A 4 pass version, but no reply. I believe AWR will do it for me if I provide them with the dimensions and locations of the spouts, drain, filler neck and maybe one of the burp things on top.
Any science majors or engineers know how to calculate what the trade off would be by loosing height and width but going deeper (if possible), hopefully more efficient core (not sure if I can get one done in brass), sealed ducting and a more powerful single or two small fans?

I haven't been able to take measurements and call AWR but I think it would be more effective then the tiny openning on the SMIC which is like 1"x6" as well as the radiator since this way air is forced through both. The v-mount is a compromise, be it better then the SMIC setup. Both the IC and radiatorare at angles, so even with proper ducting it does not have efficient air flow.

ive seen a couple of cars in the last couple of weeks with an FD style setup. basically the GIANT IC gets mounted where the radiator was, and the radiator ends up front mounted, kind of like a stock FD.
the bonus is that the IC pipes are really short and straight...

That would be the large M2 or ASP SMIC. I want to reverse it (switcheroo). Actually what I want to do is a FMIC setup but the difference is I want to make a radiator the same wide and short rectangular shape as the intercooler (of course not as deep).
If you look at a stock or even a large SMIC's duct, the opening is extremely small. So only when the car is on motion will it be cooled off. Pettit Racing now has a fan for theirs for city driving. Even at speed the openning is very small. It's something like 1x6 or 2x8? which is not going to get enough air to flow through the entire face of the cooler (in my opinion).
In this way, sheet metal can go all around it. It would shroud "both" the FMIC and radiator enclosing both like a tunnel. This in turn would force the air exiting the FMIC to go "through" the radiator.
