I'd like to use the LTC2865 RS485 tranceiver since it has VL to that I can easily interface between 5V and 3.3V domains. But I also need half duplex mode. Is it possible to connect the 2865 in a way to acts like half duplex of the LTC2862? Is this a reasonable line of thinking?
You could use LTC2865 at half duplex mode, tying A to Y/B to Z and controlling DE and RE for signal driving or receiving purpose.
