Room for 16+ SpeakerLink + 16+ optional analogue? I doubt it somehow. I think it may be an either/or option but not both. Or another box of course.

Edit: It's also possible that it may not be deemed necessary to have separate SpeakerLink outputs for of each height effect channels and that some could be daisy chained.

Main system - Sources (Kodi-HTPC, Vero 4k, FireTV, Sat) into Trinnov Altitude 32 (8-16) (+Roon), Trinnov Amplitude 8 amp & Vivid Audio (Giya G3, V1.5) and REL Stentor III speakers. Others: F80 + Raspberry Pi and other Pi systems.
