What I'm talking about is "replacing" the fat hose shown here that goes from the IC to the intake manifold.

Why?
What would be the point.
You NEED that sigmoidally curved hose to absorb the flex inherent when the motor moves on its mounts. Adding a second cooler in series would not help you any there, and would probably lead to the death of both coolers. The end tanks would get cracked by motor movement and vibration.
Adding two coolers in series is generally a bad idea. I know the 225 hp TT does it, but that was mostly a packaging issue.
That is a lousy location for a cooler, as there is NOTHING to support its weight, except the cooler hoses themselves which is bad bad bad. Also it would breathe poorly if at all, and would get hot air already passed by the radiator.
Not to be an ***, but its really not a very good idea. But new ideas are always welcome!
Get a FMIC and I think you will be happy with the results.

"You NEED that sigmoidally curved hose to absorb the flex inherent when the motor "
You are correct, I had thought of that, and desided both ends of a additional cooler would be connected by flex joints.(simply a short length of tubing)
"That is a lousy location for a cooler, as there is NOTHING to support its weight, except the cooler hoses themselves which is bad bad bad"
Acutally, on my engine there is at least one m8 hole right under the area im talking about(on the engine block)...also in that same area there is a cast thru-hole/bracket (for god knows what) that is not being used.
On the last picture you can see that that area actually gets fresh air flow from the radiator fan area...(Though admittedly this will probably be warm air from the radiator)
I just threw the idea out, so I could get critical responses bringing up issues i hadnt thought of...
I welcome your response, thanks.
(my real intention is to engineer a solidstate cooler...BTW I am a mechanical engineer)

you mean air-water-air
People keep referring to them as water-air and pointing out how water can transfer heat 13x better than air. Well, that's fine, but the problem then becomes one of cooling the water. And guess what, you are stuck as bad as before trying to cool it with air!
Air-water-air systems are only useful where you can't get the intake air near any airflow.
Why doesn't anyone do a compressor-based system (freon?). Those don't just move the heat transfer to a different spot and instead actually do produce increased effeciency.

Must have something to do with the fact that AC requires power to drive it!
For a guy that's awfully damn picky and spends all his time correcting everybody, I'd a least think you would have all the answers.

Re: A side issue...
Ever wonder why Audi/Volkswagen designed contortions into that hose?
The IC to TB hose also functions to absorb vibration/movoment between the IC (a stationary object) and the engine (a non-stationary object). For that reason, I'd look at other alternatives for reducing charge temps.
$0.02
