Second, I agree with wazoo. The tail should not wag the dog. You are the one who has to literally live and die by your decisions as a company, and your track record indicates you know how to survive in a tough industry that leaves more than it's share of corpses along the road side.
That said I will submit a few opinions for what they are worth.
First, the one thing you could and should do is have better quality control at your factory. I see many of your drivers, and sometimes they are works of loving art, and sometimes they look like a trained chimp assembled them - tension buttons crushing the mylar, wires buckled so they are lifting 2 inches off of it (and I'm talking brand new speakers) and in some extreme cases the mylar itself so mis-applied the speakers could not possibly play right. This should not be happening, especially when people cannot "pop a dust cover" and examine the drivers they are buying as if they were a conventional speaker. We have to assume you did it right, and the fact is sometimes you are not.
That's really it. There are things you do I could question, but I won't. For example I could say we would all prefer you found a better adhesive so that delamination would not occur, and I am convinced such adhesives exist, but your company loyalty to 3M may have deeper implications than we are aware of, and you may actually need the refurb money to help stay solvent. So while we'd obviously like to see this problem end, it's not like we don't know what we're getting into and we still step in the boat. We also do not have to walk in your shoes.
As far as the improving argument, that would be the biggest mistake you could ever make. Your dealers already don't stock every model, and what, there will then be an MMG, and improved MMG, a "super delux" MMG, an MMG with "special option 8F" etc... add to the fact this could apply to 5 different models, who could possibly stock such a line? It would cause confusion, cost you and your dealers a fortune and people would STILL tinker. People don't understand your costs when they make such suggestions, as altering products on assmebly lines cost money and time. And what will these people do when the price of the 1.6 jumps to 4 grand and the parts inside are still not what they wanted?
No, just continue to do what you do, just watch the quality control, and things will be fine.
As far as what people would "like to see", I think the tinkerers would like to see you offer your drivers just so. This would only be a factory direct offer, but if you sold the drivers for your models at half the cost of the regular speaker it might help sales because some people don't buy because retail plus the added cost of "upgrading" is sometimes too much.
Second, many people don't have the room for the larger maggies and are interested in this small offshoot of the 20's technology. If you could price that around what the 1.6 is, I think they'd be very happy, it would sell well, and not effect the 1.6 sales because no matter how good it sounds little ones do not have the same presentation bigger ones do, and many are partial to that presentation.
That's it, other than I wish to thank you from the bottom of my heart for a speaker technology that brings joy to every single day of my life.
It's all about the music...
