Without all the considerations of engineering problems,
Is it aerodynamically advantageous to eject hot air into the wake to reduce drag, this being for both cooling system and exhaust?

So really, is there any significant aero benefit possible with this idea to warrant spending the time required to overcome the engineering and design issues?

Is this a serious statement? The Lexus LFA!!! Not my favorite or even preferred high performance car, but for manufacturing and technology, it really is fantastic.

I don't know if it is better for cooling, but from what others have mentioned, it seems so. And it makes sense to put the exhaust in a low pressure zone, and pull it from underneath the car, I would expect creating downforce.

Significant, I think so. Reducing drag up front, increasing downforce at speed, and helping the wake. Just looking at these individually is probably fairly small, but combined should add a bit. And other than that initial build for the LFA, the design seems simple. Once they figured it out, it should be good.
