I would recommend buying an old school reissue since they have somewhat new school shapes while retaining old school size.
There are also some longboard companies that work with shorter lengths and traditional surf/skate shapes.
Here is a good place to check out.
The Longboard Store
Element, Gravity, Old School, Surf One, and NOS (Sector 9 Crushers) all have shapes and sizes you'd probably enjoy.
You can use longboards wheels on a basic setup as long as you have clearance, but you'll *potentially* lose a bit of stability depending on truck size.
