Replacing B&W HTM3 tweeter cone

I'm trying to figure out what's the easiest way to fix a deformed tweeter cone of my B&W HTM3s center speaker. It is clear that functionally the speaker is unaffected and the tweeter is only cosmetically impacted, but I would still want to get it fixed.

Now based on the parts that I saw on B&W Support website, I can purchase the entire tweeter ($228) or just the cone assembly ($128). I have no idea yet on how to take out that cone assembly from the tweeter to just replace that or if I need to remove the entire tweeter to replace that little cone alone. I actually unscrewed the 3 screws around the dome, and I can tell the whole assembly is moving forward, but I'm afraid to pull it.

Does anyone here has experience replacing such a cone and help me with some ideas? I can't find any relevant video online.

The assembly might be easier but you probably have to take out the midrange to get to the assembly screws. I would assume it is screwed in from the inside. 
There also might be beauty ring covering the actual screws of the driver. Some videos below that might help.

If the issue is just cosmetic, you should try a vacuum to suck it out, or disassemble it and use your fingers.

Yeah, so I ended up following the examples in one of the videos posted above:

I removed the cone and use my fingers and the eraser at the back of a pen to push it back and smoothen it out. You can definitely tell is not perfectly smooth, but at least is not pushed in anymore.

Thanks guys!
