In theory, you do this with a stacked DRBD setup.
At the top, you replicate from your active node to the peer using
protocol C.
The peer now replicates itself to node 3 via protocol A.
Handling switching from one to the other may be a bit annoying, and you
may run into issues with the kernel stack size on the intermediate peer,
but in theory it ought to work. ;-)
