In theory it should work, but you'll gain little, because only one 
user can access the uplink.  Only advantage would be to stations with 
Rx setups not up to scratch for receiving SSB, that might resolve CW.

AO-16 is running FM up/SSB down on a permanent basis.  It is not 
running any digital modes these days.

I'm not familiar with the state of digital operations, as I have 
little interest in the current state of digital satellite operation, 
and also find the hardware requirements to be a pain, because that 
requires a fixed (or at least one that you can't operate while 
wandering around) station, and I have traditionally operated 
portable/pedestrian mobile/movile on various forms of public transport.

There's a number of people on here who can advise the best route for 
digital ops.
