Very, VERY bad idea.
There is a reason why it was discontinued. The rubber ball-and-socket joint at the arm-backrest junction degrades quickly over time, dislocating suddenly, and sending the seater crashing to the ground backwards, head first.
See photo. Imagine the backrest suddenly detaching when you are in full recline mode.
Either include a helmet with your kit, or have a really good lawyer.
Even possible?
I don't know that anyone would want to, but even if you did, I don't see how you could do it (modify a contemporary DAF to make a MAA). I have not inspected the new DAF chairs, but I assume that the seat and back are injection molded as one piece now as opposed to the vintage chairs which are 2 separate pieces glued together. If you could remove the back from a new DAF, how would you fashion a new MAA back? It is much larger than the back of the DAF. You would also have to fabricate the rubber mounts for both the arms and the seat back not to mention the metal attachment. Seems like a lot of work.
While I appreciate the idea of the MAA, to my eye it is not as elegant as the DAF. With the large, broad back it looks a bit ungainly next to the DAF whose shapes all seem to compliment one-another.
While the vintage MAA chairs were prone to failure when the rubber mounts got dried out, I'd think that plastics and rubber technology has advanced enough to where the design could be realized today without the same problem.
While not a workhorse like the Eames armshell, I think the DAF is a much more beautiful design.
