I very much doubt that W3LPL told you that! His BPF are triple tuned
circuits with top capacitor coupling. They exhibit low impedance on the
frequencies above bandpass. 10 m filter is coupled to 50 Ohms with 33 pF
while 160 m has 719 pF. That gives 475 (square) power ratio or -27 dB
loss.
Only serial tuned circuits can be paralleled at 50 Ohms and even that
becomes difficult beyond triplexer. Check http://www.nuhertz.tv/
You don't need any BPF for QS1R, just band STOP filters to prevent input
frying from nearby TX. ICE filters might be easily converted to band-stop
with change of both inputs to serial notch and adding just one more small
coil for parallel resonance (de)coupling.
