I dont think you can do exactly what you are asking, however, one workaround to have the delayed signal with some filtering is to use the bright/dark parameter of the delay itself...this is actually a LowPass filter (as you turn to the left) and a Highpass ( as you turn to the right), but unfortunately without resonance...
but still, a great effect, and a lot less troublesome than doing all this routing around...
