I'm not sure if it's the same display or not but potentially you could use something like that - it's got the battery/charger/etc and is pretty integrated so might allow you to get things a bit more compact.
Or... not sure if you spotted http://forum.espruino.com/conversations/360918/ but you can run Espruino on the MDBT42V (which is insanely small). I'm in the process of getting some of those pre-flashed to stock in the shop.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
Wow, that's great! So it's just an OLED display?
I was wondering why you had that UI library for Bangle.js ;)
Just a thought, but did you know @fanoush has done a port of Espruino to the DS-D6 (and a bunch of other stuff too): https://github.com/fanoush/ds-d6
