Nope. Won't work. Different sort of clinch.
Drop, while I disagree witht he O/P use of the word "Nobody," and I totally agree with you that a Thai clinch is a serious problem to deal with (I loved to use it and did so all the time), I've had a simple kosotogari or kosogake take us (my opponent and i) both the ground before as Wang said above. One way to think about the Thai clinch is that it's a posture breaking device, used in a stand-up striking art to tear down the opponents structure, and keep him off-balance while you damage the begeezus out of him with your knee strikes -- or you can just use it to take a breather.
I was stubborn, and stuck to my technique even though I was doing some free-fight traning with some other guys, just having fun, seeing who could pee the farthest, like that. One of the main reasons I ended up in Judo was this guy who had watched me "end" a couple of the fights with just this clinch, by figuring out the other guys movement and striking patterns, sliding inside their guard with a combination and allowing them to fall ihnto the clinch. Then, it's all over but the crying, I used to say in my arrogance. *shrug* Everyone learns humility, sooner or later. I think I've had to learn it about 17 times and I'm probably due for number 18 any day now.
Anyway, judo guy asks me to work with him, and I said sure as he had some golden gloves in his background. We went back and forth a minute or so, he scoring on me with his better than my boxing skills, me sorting of making his day worse with the leg kicks, even though not so hard, and then I got the combination I wanted and he fell into the trap of the clinch. I thought.
It went on, I locked it down and applied the locking angles, bringing the judokas head down and to me (any judo guys out there can start laughing now, I know now what I just did), and the next thing I know I'm first on my butt, then on my back with an indian carpet laying on me and really not so much in a clinch any more.
I figured it out after a couple more times, but the vulnerability is right there. It's just not there in a Thai-boxing match, as it's illegal. Clinch goes on, opponent goes with it (ju) and ends up literally under the constriction of the clinch, maybe gives up a little skin, but then it's an easy leg vs. leg technique. You can almost pick one, especially the sacrifice ones.
I trained witht he judo guy off and on for a couple months, and ended up with he and I working through a transition technique of sorts, which, depending on how I was attacked, ended up with my clinch still on, for what it's worth, and holding a guard or mount position depending on where we went, but very often it ended up being a half-guard I'd managed to snag on the way down.
And that, my buddy, is how I got introduced to BJJ as a next step.
