Exit pupil is overrated. I believe any self-respected astronomer should have 3" EP to go along with sextuplet APO.
Do you mean a 6-element APO, or 6 APO's? My vote is for the latter... ;)
Telescopes: 12" f5 dob, Celestron CPC800, 150mmf5 Celestron achro, Tak TSA102, TV76, ETX125...
Binos: Steiner Wildlife XP 10x26, Swarovski 8x30 Habicht, Zeiss SFL 8x40, Vanguard Endeavour 10.5x45, Fuji FMTR-SX 10x50, Tak 22x60, Orion Resolux 15x70
Eyepieces: way too many (is that possible?), but I do like my TV 32mm plossl, 13mm Nagler T6, 27mm Panoptic and 3-6mm Nagler zoom, plus Fujiyama 18mm and 25mm orthos and Tak 7.5mm LE

I think six 6-element apos with lenses cut in hexagons allowing for hexagonal OTAs with resultant easy stacking and storage would do the trick! ;)
