Why do you think this proposal wouldn't work to mitigate such an outcome?
I don't even understand that proposal but from the little I do understand, I don't see how it relates to changing the maximum block size. Maybe you could rewrite it in more clear, formal terms? Here's an example of my proposal for changing the maximum block size:
1) A boolean flag is added to each block. The flag represents the block solver's yes or no vote for increasing the block size. The independent miner or mining pool sets this flag according to their preference for an increase.
2) Every time the difficulty is adjusted, the number of yes votes is counted from the last adjustment. If the number of yes votes is greater than 90%, then the block size is increased by 1%. Both percentages are baked-in constants, requiring a hard fork to change.
See how it's concise? Try to mimic that.
