Hindemith's Fünf Stücke für Streichorchester, Op. 44 is not a violin concerto per se, but it does have a final movement that is basically a "mini-concerto" in itself, for solo violin riding over the ensemble the entire time. The piece was designed to be played by younger players, and sounds much more complex than it actually is.
Not sure if it's exactly what you're looking for, but well worth considering. The best recording I know of that is readily available is with Werner Andreas Albert and the Tasmanian Symphony Orchestra (on CPO).
