Default Implementing of Active Crossover Network after change the Mode from Aleph Power Amp

If I transform any Aleph model from the non inverted mode to the inverted mode, it is easy to implement an active crossover network with 12db/oct (only MFB resp. Multiple Feedback topology, not the Sallen-Key topology).
Are there any experiences in this matter?
Here an URL:
Design and Dimensioning of Active Filters
Cause the lower open loop gain in opposite to typical OP-AMP's there must be some additional design rules.

You can treat the amplifier as a big hot op amp if you like, so I assume you
could do it easily enough.

Yes, but nevertheless I would like to know audible experiences from user's of existing projects in that kind.
