Mike, when I came up with the cabinets I figured most would just place the networks on top of the bases behind the lower M165NQ ( why we left a bit of extra space below that lower woofer.) Basically it was the same idea as the full size Otica's and Wedgies..
Figured if some wanted to hide them, they'd get creative as you've done Unfortunately, you have the one little glitch in your layout
As for that inductor, I don't think you'd actually notice any obvious change, it'd be subtle but you may have some slight interference and a difference in the response.
that last layout is about as good as you're gonna get without flipping at least one inductor on it's edge
If you re-wired it and put the large low pass inductor in one corner, the tweeter inductor in the opposite ( on diaganol) corner and the small LCR in between them on it's edge, you may have enough height clearence . not sure
