A few thoughts:
1) If you can load a revolver faster with a speed strip than you can with a speed loader, you need to seriously work on your speed loading technique. I have a post here recently in another thread discussing the traditional, FBI, Universal and Stress Fire methods of reloading with a speed loader.
You might want to do a little research on the topic. It's hard to beat the FBI reload for speed, but if you've got a short barrel revolver with a shorter than standard ejector rod, and the cases for your self defense loads stick bit in the chamber you'll want to focus on the Stress Fire reload.
2) There are better options for concealed carry of a speed loader than the traditional police duty belt inspired pouch.
There are a couple models that slip over the belt, so that only 2-3 rounds extend outside the belt.
This one is made by Wild Bill's Concealment in Garner NC for the J-frame revolvers. You can carry it with either 2 or 3 rounds inside the belt:
3) I shot in a local practical pistol match this week, geared toward the casual concealed carry shooter - mostly a local concealed carry instructor trying to get concealed carry permit holders to shoot more under a little stress and time pressure in closer to real world conditions. To add a little challenge I shot my Model 13 with +P loads. It's a challenge in a stage with a long course of fire geared toward high capacity semi-autos.
I recommend that kind of shooting if you plan to carry a revolver for concealed carry as it will get you thinking about what might be the best reload strategy for the situation.
4) The concept of lifting the ejector slightly to lift the fired rounds, in hopes that they'll stick up so you can remove them, and then reload the empty chambers with a speed strip is not the most well thought out idea I've ever heard. I'm trying to be kind here.
When you lift the cartridges with the ejector rod in this manner you run the risk that one of the rounds will drop down under the ejector star, which will a) prevent the cylinder from closing again, and b) will be a real mother of a jam to clear under stress when your fine motor skills are toast.
Try doing it quickly standing still, then try to do it while running toward cover.
Then try doing it in a hurry while running toward cover while keeping your head up and your eyes on the assailant(s).
You'll probably conclude that it is a total non-starter of an idea.
5) The choice when confronted with the eventual need to reload is often not how many to reload, but when. Consider for a minute that you've engaged one assailant and you're moving toward cover to engage another. You obviously fired 3-4 shots and you have 1 or 2 rounds left in your revolver. Do you want to eject them while you're moving to cover and have the time, or wait until you fired again, and take the chance of not having enough rounds left to finish the sight.
One round versus two might make a difference, particularly depending on the circumstances, how many more rounds you have and how many more you think you'll need, since you'll be leaving 1 or 2 rounds of your limited supply on the ground.
It's also going to depend on how well trained you are in using a speed loader. If you've good with the FBI, Universal or Stress Fire reloads, doing it on the move isn't an issue and it can be done by feel with your eyes still in the fight.
6) Loading two rounds with a speed strip and getting back in the fight is better than nothing, I suppose, but it takes as much time as reloading all 5 or 6 chambers with a speed loader. It also has the added problem that you have to index the rounds you just loaded so that they'll be ready to fire the next two times you pull the trigger. It's hard to do that by feel so you'll be head down and unaware while you're doing it.
