How would it work exactly? Let's say there's two chains:

Block A - 210kb -> Block B - 300kb -> Block C - 582kb

versus

Block A - 210kb -> Block D - 175kb

Doesn't sound like it'll work well.

Is there demand for a solution that will (hopefully) solve the problems below? I ask because I don't wish to bother the devs with an incomplete and useless proposal.

BIP RFC: A solution to the block size limit?
Changes
This solution requires several changes to the Bitcoin system:
  • The block header has an additional field added to it: the size of the block.
  • The algorithm for chain length is changed. See below for details.
Strengths
There are several strengths in this system.
  • There is no need to increase the size of the block limit.
  • Clients do not waste bandwidth downloading large blocks.
  • Block sizes will be regulated through risk and reward, that is, by the market.
Weaknesses
There are several weaknesses in this system.
  • A 51% attack is more dangerous, as miners have more control.
  • A 51% attack may be easier to conduct, as the attacker could mine empty blocks.
Concepts
This solution relies on several properties of the Bitcoin system:
  • The length of a chain can be determined through only the block headers.
  • The block headers are of a fixed size.
