My objective was not to create a clone of the LS 3/5A but a DIY which would sound close to the capabilities of my floorstander. Benefits include cost effective replacement of parts and ease of doing so myself.
The following are the resultant after purchasing the necessary parts.

Since the Monacor MDM-2 and my hybrid insulator were available, I took the opportunity to replace the make-to-do foam in the LS 3/5A cabinet with them.

How does it sound?

I would say a more open and natural presentation than the replica crossover. Headroom from the presentation was a revelation when compared to the output via the replica 11ohm crossover.
For the first couple hours or so, there was no bass. Slight hint of bass was produced after the first couple hours. As time progresses, the presentation changes progressively. More bass was audible after 20hrs and again after 30hrs.
After about 40hrs of run-in, the presentation is with good detail and pleasant for hours of enjoyable fatigue-free listening. Bass from good recordings are reproduce with realism as well. The English accent is still present but not as strongly enforced as via the replica crossover.
That really made my day!
