Some discussion today led me= to believe that a post segwit hard fork could include:

= 1MB old tx non-witness segment
XMB new segwit non-witness segment<= br>
XMB witness segment

By partitioning off old transacti= ons, it allows users of older, more expensive validation transactions to co= ntinue using them, albeit with higher fees required for the restricted spac= e.

New segwit blocks, which don't have the hashing pr= oblem could be included in the new non-witness segment of the block.
