There are several blackberry keyboard projects out there. I've been on a similar journey to OP for a while. Currently I've got a phone I'm fiddling with putting a jetson xavier inside a rotary phone and another based off the featherwing with a blackberry keyboard and touch display and a feather compatible linux SOC (GiantBoard).
I recently got a ClockworkPi DevTerm and have been so pleased with it that I'm seriously considering their GameShell as a phone platform. It's modularity is great.
I'm so excited that other people are working on DIY "phones". I personally think we are going to see this scene keep growing and phones will finally be more like the custom computer market very soon. The fact that people are finally putting linux on apple devices is also very very encouraging. There are so many bricked iphones and ipads floating around with great displays and sensors that are totally useless because we can't run a reasonable OS.
