Use -af pan to downmix to one channel (without combining any channels). 
I.e.:

   -channels 6 -af pan=1:1:0:0:0:0:0   channel 0
   -channels 6 -af pan=1:0:1:0:0:0:0   channel 1
   -channels 6 -af pan=1:0:0:1:0:0:0   channel 2
   -channels 6 -af pan=1:0:0:0:1:0:0   channel 3
   -channels 6 -af pan=1:0:0:0:0:1:0   channel 4
   -channels 6 -af pan 1:0:0:0:0:0:1   channel 5
