Default Bluetooth connection while in bootloader

As you might know, the bootloader of both the LG G Watch and the Samsung Gear Live can be unlocked.

This is necessary (at least for now) to root the watch an there is even already a first custom rom for the G Watch out there.
However, this requires a direct USB connection to the Android Wear device.

The Moto 360's specs are still unknown, but the device won't have any kind of wired connection.
Is it (theoretically) possible to set up a ADB connection to a Android Wear device over Bluetooth while in bootloader?
