Hole in NS-1000M midrange driver

I just acquired a pair of these speakers in fair condition; all of the drivers look good except the right midrange driver. There is a small hole in the dome! It appears to be around 3mm in diameter. The image is rotated; the damage is actually on the middle bottom of the dome.

Is there anything that can be done to salvage the driver? Am I right in assuming that the driver is unusable in it's current state? Do I have no choice but to pray for a replacement to pop up on eBay? I've read that these drivers were assembled as carefully matched pairs. Will there be a significant imbalance if I do end up buying a single replacement driver?

If I do happen upon a non-functional driver with an intact dome, is there any way to Frankenstein them together?

Any help would be greatly appreciated. Thank you!

Beryllium is toxic if aerosolised, when solid the metal should not present a danger to you. Nonetheless it would be wize to wear gloves when handling this alloy.
I agree with those who say try it out and see if the small defect has any effect on the sound. If not just use them.
