This may be dumb but could you use varactor  diodes in the filter circuit and vary the voltage to them to change the capacity in the circuit to vary the band width. The Electraft K1 uses this type of adjustable filter  routine. Years ago I copied  it and used it in a TenTec  1340 kit and it worked pretty good.
