To explore a very specific question about whether widespread double-spend relay will result in miners more likely to mine DS, I wrote a crude simulator. It does not account for lots of variation in a real network, but I think it's a place to start.

Apologies for writing in Matlab, but this is the only thing I'm good enough at to cook up in an afternoon. It *should* run on Octave, but let me know if it doesn't.

The preliminary results might surprise you! Whether relaying immediately or with "trickle" logic, I found that DS relay does not seem to increase risk of tx2 mined over tx1. It might even improve it a tiny bit, though it's too thin to be significant.
