You could try editing the following config file to set a different rate and bit depth and then turn on Bluetooth speaker sharing in Audio Config. This will cause bluez-alsa to use btaplay_dmix device defined in the .conf file instead of defaulting to the plughw device.
/etc/alsa/conf.d/20-bluealsa-dmix.conf
I don't know what ALSA uses by default for resampling but it's prolly not going to be great quality like SoX.
