In my head this works, but will it actually?

Could anyone tell me if this is theoretically possible...

I have an ESP wrover kit which has built in Bluetooth capabilities and an SD card slot. I want to insert an SD card with a sound track uploaded onto it. Next, I want to setup another ESP32 device, but this time with an added speaker. The ESP wrover kit will send the sound track via Bluetooth to the other ESP32 device and then eventually playing it through said speaker.

Basically I want to gimmick the wrover kit as a phone (store music on it which connects to a bt speaker, in this case another ESP device) and play the sound through another ESP via BT.

The reason I am doing it this way is so I can use Ardunio to edit the bluetooth code at a later date, for instance changing the connection time to force restart if its >60 seconds.

That is doable.

Thank you. Do you have any recommendations for a ESP device that has a built in speaker already, but can also allow me to modify the code too? If not, no worries I will have to look harder lol.

I've never heard of an ESP device with a speaker, but it is no problem at all to add an audio amplifier and a speaker. As shown here: ESP32 Walkie-Talkie - Hackster.io

That project is not Arduino compatible, though.
