Well the aluminum might be a bit harder to braze :) I think they use a
pretty standard 8% silicon casting alloy for dmls.
The smallest standard AS-5202 fitting I have seen is a -2 in Stainless, but
-3 to be the smallest size I had seen in aluminum. The straight thread is
hard to find so what you can do is just cut the tapered end off an AN
fitting down to the threads and add the orings. McMaster sells the o-ring
as 900 series, for a -3 straight thread you need a 903 o-ring. ie McM #
9752K113 <http://www.mcmaster.com/#9752K113> with an aircraft spruce -3

How small can you get AS-5202 fittings?
I've used the 10-32 fittings and the flow path is just slightly maginal
for the fuel...

Parker has a line of male AN fittings that include a teflon seal in
the 37 degree face. I expect it's possible to print one. I haven't had
the chance to prove it yet.
Anodizing the part will help make it possible, in addition to making
the regen portion a lot easier.
