Sounds overly complicated...

What about a much simpler solution where the miner has a CPU in a well 
connected data center. Say, Amsterdam.
He runs bitcoind on there and he, in China or such, connects to it over RPC 
(and ssl) to get a "block 000f00" accepted signal. Which would be 100 bytes or 
so.

The miner continues to use his current setup, but with actual validation of 
the blocks to completely eliminate the risk of mining on orphaned blocks and 
at the same time remove most of the cost of larger-than-average bandwidth in 
his country.

A slightly more complicated solution is needed to allow the miner to only send 
the headers to the bitcoind instance. So he only sends a couple of kb and his 
datacenter machine does the actual propagation.

If the risk of duplication becomes an issue, setup multiple propagating nodes 
on different sides of the world.

Bottom line for me is that most of the innovation for making stuff better for 
miners should be done in miners-specific software. Not in end-user software 
like bitcoin-core.
