High kicks: I don't understand why they would be "easier to see, faster to react to, easier to defend". You make the kick easier by not having it to be as high as usual. So since the kick is easier to do, it's also faster and more powerful...
Mid kicks: I am one of those people who are against the notion of blocking mid kicks with the arms. I understand that some people are ok with it, and even use it efficiently, but if we talk pure MT, it's not the rule, but the exceptions. When you learn basics, the defense to mid kick is simple : check. In KB it may be different, specially since blocking kicks with the arms doesn't give points to the opponent, but even there, switch hard kicks to the arms is a regular strategy against heavy punchers (buakaw vs zambidis)

For low kicks, you can turn the knee into the strike and bend your knee, so the angle of your thighs is in a way that a 90° low kick wont do as much damage, and the leg might "slide" up to the hip, making a catch possible without reaching down low. (again, Zambidis did that a lot in KB). But it's kinda easy for the opponent to adjust and make a downward low kick.
As you said, it's not the best option.

I fully (but respectfully) disagree. The only way to be in a good position in the MT clinch (when both fighter know what to do), is to have your hips close to your opponent and be on the ball of your feet. If you have a low stance entering it, you either have your knees bend or your waist bend. In both of those cases, if the opponent has a hold of your head, he needs a lot less power to make you bend your face forward and low (into a knee).
Yes, having low stance make its harder for him to make me move my feet, (and trip) but a lot easier to make me bend at the waist.
For the option to go low and suddenly "pop" up, is not something i have tried, (i will) but it seems too risky.

Since it's not something i do, i can't tell you about that. I would have to train it a lot that way, to be able to compare it with my "regular" kick.

I am not saying that a low stance won't work in MT. But it's an exception, not a rule. And in my opinion, to be good with a "exceptional"" style, (in any sport) is for "exceptional" people. Roy Jones Jr in boxing for example.
But, i am also in favor of having fun... so if the style you have is making you enjoy the sport, don't listen to people like me, and do what you want. Just be sure to master the basics first, and then go crazy...
