Idea about LTR Data Dicer

Okay, so I'm sitting here bored waiting for the components I ordered to arrive so I can build this thing, when I had what feels to be an idea...

Instead of building this circuit here could one not use a regular 2 level slicer, and install a low pass filter (crossover) for use in car stereos inline with the discriminator audio cable going to the slicer? Wouldn't that perform the same function as building this entire circuit?

I was thinking of these here F-MODS In-Line crossovers.

They come in 50, 70, 100, 200 and 500Hz flavors in low pass.

Let me know if I'm just plain dumb but I don't see why one of these wouldn't work, say the 200Hz one???

Their group delay characteristics are not going to be optimal.
