You keep your Emotiva XPA for the bass panels ... and build an F5 for the mids+ribbons - or an F5 for the mids plus an F5 for the ribbons (ie. 3-way active).
Even then ... you may find (although the only way to do this is to borrow other amps, to compare) that the F5s aren't really powerful enough. :-((
Why do I say this? Because for about a year (before I then got rid of my Frankenpans) I used 2x 40w-into-4-ohms AKSA 'Alpha Nirvana' Class A
amps on my mids & ribbons. Actively driven. (You can find the AKSA AN thread on DIYaudio.)
Hugh Dean - the designer - came over and had a listen; he knows my system well and admitted he was a little 'underwhelmed'. :-(( Which surprised him - as he knew how good the amps should sound.
Yet when he came over subsequently - to listen to the same amps driving my new 'zero baffle' spkrs - he was amazed at how good the amps sounded.
My conclusion was that ... although my ANs were the "4 ohm" version (to optimise their delivery into 4 ohm spkrs rather than 8 ohm - and they are stable into 2 ohms!), the Maggie mids & ribbons really needed more power.
The Pass XO should be ideal. I myself (nearly 30 years ago) used Rod Elliott's P09 L-R XO circuit (modded to provide 'Maggie' slopes) - which worked well.
