I think it would be cheaper in the long run to construct adequate detention facilities near the border(s),so that those captured by the Border Patrol could be held for a few days (or weeks) until they could be "re-patriated".
I would also add more Hearing Officers,and have them set up shop right inside the detention facilities.
My home county did this (they called it "have gavel,will travel")and it was an enormous success: There was no need to assign deputies and vehicles to transport detainees to court (unless the detainee was actually going to trial).
