For above 550hz you might use the same LL1627A if you wish, for MF the 200-250mA gap will be fine. Yes it would be reasonable to desire less inductance in the transformer, mean less turns but honestly I personally did not detect that it very much affects sound, at least in context of the S2 bandwidth.
I had to be said: “…but honestly I personally did not detect that it very much affects sound, at least in context of the S2 bandwidth and in context of the right S2 driver” .

Mark, one more think that you mostly likely do not know now but should consider and be aware. When you go with MF amorphous core with reduced amount of turns then that transformer will be lightingly fast, capable to handle tremendously articulate transients.  The Vitavox S2 driver is a very transiently venomous driver itself and it is highly possible that your S2 driver with you Milq MF transformer mighty be too much. I said “mighty be” not “will be” because there is catch in there.

Vitavox S2 driver is available with different type of magnet (I think it was 5 different Alnico types) and with 3 different diaphragms.  You will not be able to use any other diaphragms then plastic-suspended with your amorphourised Milq and you will need to spend a LOT of efforts to align those diaphragms. However, you have no control on knowledge what magnet you get in your driver. Here is the ketch - with some magnets S2 driver and amorphous Milq is just not throw absolutely unmanageable sound as it will be too fast and too incorrect.

So, beside dong over the troubles to pay the exuberant amount of money for those idiotic vantage S2 drivers you very much could come to observation that YOUR given S2 does not do well for you. From this perspective the 288 or 2440 are well more stable and secure chooses. Let me give you an illustration. I own 12 Vitavox S2 drivers and only 3 of them are able to work with Milq’s MF channel and to sound as I would like then to.
