I would try it, is that's your thing. Don't skimp on the flare and bender. I would think that if you're at a point where you need $500 or more in OEM brake lines then you might come out ahead. If it's only for one line then I I think you'd be frustrated with 75 dollars in steel and a crappy 75 dollar flare/bender tool. Eastwood or utube may say it's easy, but it isn't.
I've made lots of oil, air, and fuel lines, but always LP JIC (AN). In spots where I've been stuck I went to a hydraulic shop and showed them what I needed for a special press fitting, they just won't or might not pressure test or cert it for you.
Being in anchorage I'm sure you could take it a boat yard, or hydraulic/fitting shop. Just like in the gulf states where we oilfield trash frequent.
