If your current hybrid platform pedals have screw/bolt -in reflectors, than you should be able to attach the MKS Half clips.

However, I don't think you'll gain much from those small clips. In my experience with toe clips (full size, admittedly), they would often get in the way of pedaling and I found them annoying. Plus, the half clips would not be a good transition to clipless, because the release action is totally different (pull up/back for toe clips, push/twist out for clipless).

Don't be afraid of clipless pedals.

My recommendations:
Get Shimano SPD clips. They're the cheapest, most common, and they can be recessed into the shoe sole so you can walk like a normal person, not like a chicken with protruding clips.
Get a dual-sided (platform on one side, clip on the other) pedals so you can ride in normal or clip shoes. The shimano A530 and M324's are both good.
Practice. Lean against a door, a wall, or have someone hold up your shoulders, and practice clipping in, and twisting out.
Clip out deliberately. You already shift down deliberately when you approach a stop, so clip out a foot at the same time.

Eventually you get the hang of pushing/twisting outward to clip out, instead of trying to raise/remove your foot. I've fallen a couple times because I forget that and try to pull my foot out of the clip--it doesn't work that way.
