I wouldn't want to have contaminated diff/transmission/t-case oil getting into my crank case. (Or into the air box or snorkel, if connected to one of those)
And like I said, drawing a vacuum on the gear boxes can promote water and dirt migration through the seals.
Seems to me like a bad idea.

People have done this with no issues. I personally know two people, and they haven't caused a vacuum or whatever.
Then again, it's really pointless to go through all that work. Just extend them up. I extended the rear diff up into the rear tail light compartment. The front diff breather sits just behind the driver side shock, so just extend it a few more inches up into the engine bay. The 3.6 transfer case breather is already in a good location in the engine bay, up high and out of the way. Transmission breather is a PITA to access, so I still haven't done it...but it's really not that low either. You'd have to be fording rivers all day for it to be a problem.
