Base-8 trunk cable into a Base-12 breakout module definitely won't work, as
However, both Base-8 and Base-12 connectivity can be used

and Base-12 components cannot be plugged into each other within the same
and Base-12 components are not mixed within the same link.
Since the number 12 is obviously larger than the number eight, Base-12
outweigh the density benefit of Base-12 connectivity.
