I suspect you could do it. But, as others have pointed out, it would be 1) slower and 2) unless you are a shifting god, REALLY damaging to the transmission.

It's slower for a couple of reasons. Let's say the rev limiter kicks in at 7500. If it's soft limiter it may cut fuel or spark to a cylinder or two. The engine will not simply fall on its face.

The idea behind what you want to do is to put pressure on the shifting mechanism and when the power cuts, the load on the transmission goes away and the pressure on the mechanism is enough to execute the shift as soon as the load is removed. This works quite well on constant mesh transmissions - think motorcycles. In fact, back when humfrz was a youngster it was the idea behind the first quick shifters on bikes. It does not work as well on synchromesh transmissions.

So, if you're expecting the rev limiter to cut the power so you can gently slip into the next gear it's not going to happen. The rev limiter (if it's a soft one) will usually result in the engine developing a case of the blind staggers which even in the event you are the shifting god we mentioned earlier, won't take enough load off the transmission to get the shift done. So you're sitting there with your face hanging out and synchronizers in the the transmission turning to slurry and the engine banging and popping away. Ell seven - loser.

The other reason it's slow is 7500 is way past the power/torque peak. My experience in my car is that the power begins to drop off as you approach 7000. After 7000 both of the stock engine's curves drop like a flume ride at six flags. You can push it farther, but that will slow you down. You're better off (in my opinion) shifting at about 6800-7000. That drops you down in to the mid 5000 range which is very close to the place where the engine's torque and horsepower curves intersect which is generally (again, in my opinion) where you want to be after an upshift.
