Proposal: Verify whether 50% Tx mined from SegWit activation block to block 630000 are SegWit Tx. If yes, increase legacy max block size to 2MB and SegWit max block size to 8MB.

Implementation: This proposal either needs to be implemented in next release of Bitcoin Core or require SegWit activation period restart while it is implemented & released. 

Rationale: This proposal minimizes the chance of a chain split, while sticking to the original bitcoin scaling roadmap, i.e. https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-December/011865.html
