I would try this for the woofer. Note the only resistor that's real is the green one.

Maybe this one for the tweeter, with a little more resistance added to R2

When you say coil cored can be: ferrite, aronit, wood, p-core non ferrous, etc.
You haven't got any BSC. I'd try something like 1.8 - 2.0mH in the bass instead of 0.56mH. You'll also need to reduce the tweeter level a bit, maybe a 4.7 - 5.6R resistor.
I would also try wiring the bass and tweeter in phase - you should be able to hear if you have a dip at the xo frequency if you haven't any measuring equipment.

I'm guessing here, from reading thread, that Zuhl meant Lpad (attenuation) the tweeter and not LCR (to notch).I tried 5.1R in place of 8R and I like more 8R
