Wouldn't it be possible to use your own router and treat the AT&T router essentially like a modem? I ask because I'm about to move to an address that can get AT&T fiber.

Sort-of. It has a DMZPlus mode, but all it does is assign the public IP to an specific internal device and uses NAT, as well as forwarding all ports, to make it look like that device is onthe public Internet (even though the modem has the same public IP). You can still plug in other devices and they get private IPv4s or parts of your IPv6 prefix and it NATs (the IPv4) those as well (it's to support their VoIP phones and TV service).
It's a shitty hack and it adds a weird layer of indirection that's kinda buggy and doesn't always flow traffic the way you think it's being flowed. The IPv6 stuff gets confusing as well because the modem is still dishing out public IPv6 address, so if you want to advertise them as well, you've got to start slicing up your prefix.

However, I still can't ping 1.1.1.1.
