Have you considered a TurboCommander? Not sure how the low belly would be for the strips you intend to use but at least the props are kept well clear. Or Cessna's Conquest 1 or 2? If pressurisation isn't required then a Caravan II (Riems F406 - essentially a C404 with PT6s) might be an option.
A somewhat larger option could be a LET410UVP/LET420.
