Short answer (from being in the project for 3 years) probably no. For the same reason that there won’t be a GBA Studio, GB Studio is volunteer-developed and doesn’t have the resources to focus on anything besides the Gameboy. There is a 3.1 update being worked on currently (no release date) and beyond that, there could still be more updates to improve it.
If you want more ways to develop for your Pocket, you have a whole world of Gameboy homebrew tools to choose from, and various ways to patch .gb files. You could also try learning to make homebrew for Atari Lynx, Neo Geo, or Game Gear.
