If you're specifically asking if the clamp mount for the Scala G4 Rider will work, the answer to that is "No", for the very reason you mentioned. I don't have the ST, but I do have the Evoline 2, and I had to use the included glue pad to permanently mount the Scala to my helmet. A couple notes.
1. The glue pad seems very durable, and is meant to be permanent. I feel confident it won't just fall off.
2. While the glue pad itself is permanent, it screws into the scala headset just like clamp mount, so the headset can be removed with no damage to it. However, you will need to get another glue pad from the Cardo peeps in order to mount it to another helmet.
Your second question is will you have room for a boom mic. I have room in my Evoline 2, but just barely. My gotee touches the foam cover of the boom mic, but I've gotten used to it. Obviously, the wired mic kit would work less well, since the chin of this helmet rotates up and around. For some people, the boom might be too close to the face. I think it's fine, and when a buddy tried on my helmet, he said it wasn't bad at all. You should use the more flattened boom mic cover when you use this helmet, of course.
