Anyone have a good alternative to the Pebble Core that runs some kind of open OS (Linux/Android) with 3G built in a very similar form factor? Will take suggestions from AliExpress even... Wish I would have just gotten my Pebble Core instead :/

You could strap a ESP236 to a bluetooth or NRF module- those things have a lot of processing power, wifi, etc, and add a little battery. They've got good power consumption, are cheap as hell, and should work.
