<x-charset iso-8859-1>The rear apron is a plenum. It is a storage area for air, literally. Both the fan and induction pull what they need from this plenum. The fender vents provide the air and the fenders themselves are plenums. So a source of air is not lacking for either system! You have to think how long are the carbs really at WOT? Only during hard acceleration are they open wide; cruising down the road, at 10mph or 75mph, the throttles are not wide open! So the fan is the main consumer of the air space, more so the more the engine spins, obviously. By having both intakes pulling from a storage container (the plenum) they are being supplied with their demands. The distance between them is enough to keep the fan from vacuuming air from the carbs. Putting induction intake further into the rear plenum or fender plenum isn't going to impair the fan's intake. I would be careful about the proximity of the induction vs. fan intakes since the fan could possibly steal, or at least impair, the induction intake.
