Consider trying harder to make your pump head work w/o the adapter.
I have a >20yr old Zipp disc. It has a smaller opening for the pump then current Zipp discs. There's no way I can pump it up w/o an 90deg "crackpipe" adapter, not even close. I have a couple different front aero wheels and they are either "fine" or "not fine, but do-able" w/o the crack pipe.
The fact that the Zipp needs a crackpipe is a pita. I have an old school Silca pump and it likes the old crackpipe just fine. But it was down for a couple weeks so I bought a Lezayne, only to find that the crackpipe won't work with the Lezayne. So I bought a different kind of crackpipe, only to find that it won't work with either pump. Ultimately I replaced some parts in the Silca and got it working again so the crisis was averted.
But then I had to fly, for the very first time, to an event, last month. I needed a lightweight, small "travel pump". So I did the best I could to get a decent one, but, unsurprisingly, it doesn't work worth a shit with either crackpipe.
All of this forced me to realize that the crackpipe issue had me by the balls.
I think that I'm going to remove some material from my Zipp disc so that I can get a conventional pump head to the air nozzle. My suggestion would be to either mod your wheel cover so that you can use a conventional Presta air chuck, or figure out a way to finesse (twist, wiggle, etc) a conventional Presta air chuck on to the tube's nozzle.
