If trades were batch processed say every 5 seconds, and randomized in the case of ties would that solve the fastest connection issue?

Also it just changes the nature of the game. There's no incentive to interact with the batch until the absolute last microsecond. It will still be dominated by latency-sensitive participants, just in a manner where the difference between visible liquidity and latent liquidity is even more diverged from reality (on average).

IIUC being fast is not as much of a problem as dropping in a bid and cancelling it at the last moment
