Four Focal 10K515 woofers, need ideas

So I have (4) NOS Focal 10K515 woofers sitting here from when I was deep into the diy thing back in the late 80's early 90's. They were from a large purchase made to complete several Focal 633 three way speakers from that era. I built six pairs back then for fellow musicians and audio friends. If I could find a pair of 5K413 mids I would build myself one last pair and keep them because they were a fantastic sounding speaker. Short of a miracle finding that mid driver pair to go with two of the 10K515 and two of the T120 tweeters I would still have an extra pair of woofers. This got me thinking back to when I kinda had a clue what I was doing and just enough early software to be dangerous. I primarily stuck with kits for full range speakers during that era but I did focus my personal creativity on subwoofers and bass extenders for both home and auto. Isobaric, push pull, coupled cavity etc.......these intrigued me much more than sealed and ported stuff which is what brings me to this post.

Fast forward twenty some years and two things have occurred.
1) I don't have the same mind I had then.
2) I have an ipad which is not condusive to running software as far as I know.

Understanding full well that these woofers are just that.......woofers, I am asking if some of you speaker gurus would be so kind as to look at the specs of said drivers and tell me if they are candidates for use in pairs in a unique type of enclosure like I mentioned above or do they truly belong as a solo driver in a more standard alignment? From my experience with these in the 633 kits they do fine singularly in a vented enclosure reaching down to the low 30hz range but that was a rather large cabinet. If memory serves me, when certain woofers are paired in one of those unique designs the cabinet size could be greatly reduced and it would also strengthen the overall performance of those drivers.

My thoughts on use and management is the implementation of two plate amps to set x-over, phase and output volume to match up with some nice little bookshelf speakers that image there little asses off but have nothing in the way of weight.

Any thoughts, insight or help is appreciated. It frustrates me that I use to be able to do this on my own, but not so anymore and I am learning to ask for help rather than get twisted and give up.

Thanks
