Maggie 1.2's Low End Crossover Upgrade

I recently purchased a new pair of Magnepan 1.2’s which I am enjoying very much. The tweak bug has bitten me and I have made some adjustments already.
First, I got the Maggies to stand vertical, which improved the overall soundstage. Second, I have bypassed the fuse, which has improved the clarity of the treble.
The third tweak I am considering is to replace the low end crossover parts. Specifically I have been looking at:
http://www.positive-feedback.com/Issue4/magnapan3.htm
There is some pretty good literature written by an Ed Morawski that suggests the low end crossover change will improve the bass and slam. The instructions seem pretty straight forward.
Have any Maggie 1.2 owners completed this crossover change?
Was it hard to complete? I have changed out capacitors in Large Advents so I am assuming that it is not too difficult.
Were there difficulties in physically placing the new crossover parts? Is it possible to keep them in the same place as the old parts under the sock or do you have to mount them externally?
What were the sonic results? Did it make the Maggies sound better?
Any other thoughts?

Magnepan is a DIY dream.

You may want to consider simply getting RID of the MDF frame, go to real wood and properly brace it.

I run my panels with the mylar facing the wall, which is 'backwards' from the way Magnepan intends....at least from the mid-90s on. Wood frames are in the planning stages.

I also got rid of the Chrome Plated Steel jumpers....replacing them with copper.
Sooner...rather than later, I'll do a fusectomy and at the same time get rid of the jumpers altogether while getting rid of a bunch of connections on each panel.

Try 'planar asylum' for more tips and discussion than you can probably stand.
