There is also an unbalanced moment caused by the offset, the transfer region needs to act like a 3-sided diaphragm.

What does your local code tell you? In the US, we would reference the NDS SDPWS for capacities and detailing, but if you're outside of the US, you'd want to find the applicable code requirements and checks for your specification detailing situation.
To add some more context, the blocking provides load transfer from panel to panel, so generally speaking flat 2x_ material is the blocking of choice for most blocked wood diaphragm applications.
Drift is spot on as well, you'll need to check for torsional loading with a semi-rigid approach to determine stresses in the diaphragm and appropriately detail if/where blocking is required. With a 2ft cantilever however, I would not expect significant requirements, the IRC may even allow that short of a cantilever diaphragm with braced wall lines?
