In general, having a non-standard embouchure seems like a bad idea for a beginner unless there is a very good reason for it.
I just tried it. Seemed to be fine, but I found it a little harder work to maintain the right mouth shape. But that's probably just getting used to it.
However, a mouthpiece patch seems like an easier way to create a cushion. I like the thicker ones.
I really disliked having my teeth on the mouthpiece at first, but my teacher encouraged me to do it, and now I don't think about it.
