Could you build this?
No This is a physical hardware product requiring custom PCB design, electronic component selection, firmware development, power management tuning, and casing fabrication.
What it would actually take: Requires electrical engineering to design multi-layer PCBs using KiCAD/Altium, integrating an ESP32/microcontroller with SPI e-ink controllers, I2S audio CODECs, I2C fuel gauges/RTC, and power ICs. Firmware must be developed in C/C++ (ESP-IDF or FreeRTOS) with deep-sleep power profiling, waveform driving for electronic paper, and low-latency audio streaming.
