Looks like a somewhat difficult replacement - the front baffle of the speaker appears to slide out on rods - most likely secured from the back, see the last picture on the above page.
That being said I wonder why Magico remove the protective screen that the BE dome tweeter is fitted with when procured from ScanSpeak for an example (the dome / surround looks VERY ScanSpeak) its there to protect the dome from specifically what happened to the OP - Probably because its not pleasing to the eye however acoustically it will make no difference. With their design and machining capabilities they certainly should be able to come up with something.
Best of Luck
