Well, it is not too wide to use but it will give a different impedance /resistance. The I-D tweeter is originally about 4.8 Ohm. With the smallest size foil Magnepan can offer, you will have about 7.4 Ohm, you loose about 2 dB and the mass is higher. Yes, this foil easily breaks but it is still doable. My T-IVa uses more of this than any tweeter.
I have been workning on my Tympani IIIA tweeters. Replacing the Mylar with a thinner one, cutting down the width of the driver in order to place it closer to the midrange driver etc. The driver is 20 cm wide but the diaphragm is just 6 cm. I ended with 10 cm wide drivers. I still did not like the very closed sheet metal in front of the driver. There is just about 11% of open area.
