staleg....mayby there's a solution available. I don't know how much more clearance you need but perhaps a 90 degree 1/8" NPT X AN-3 or -4 adapter like this would help tighten things up a bit for clearance? It could be used with a brake line with a straight end to keep everything closer to the caliper.
Another possible solution would be a brake line with a forged end rather than a sweeping elbow version as you have pictured. One like this?
The one in the link is a AN-4 line, 18" long, but they're available in various lengths and also in AN-3 fitting and line size.
Just a thought. Sometime just a bit more clearance is all that's needed.
