Hey Ted, wanted to bring this to your attention:
https://www.coindesk.com/new-viabtc-exchange-use-bitcoin-cash-base-trading-pair/

Looks like an exchange has made the first move to announced BCH as a base training pair. If this works out well perhaps other exchanges will follow suit. BCH has some strong financial backing and strategic partnerships (eg. SBI Bits, Jihan Wu...) in place that could help 'sweeten' a deal should say a more prominent exchange be reluctant to make the switch.

(Also any expectation of further adoption for BCH as a base pair comes with the assumption that BTC remains routinely sluggish & w/ relatively exorbitant tx fees).
