Check out our LNhealth repository (from the LambdaNative team). https://github.com/part-cw/LNhealth
The LNhealth app is similar to your desired workflow. It runs scripts written in Scheme that define the pages in the app. When developing for Android I can just push a change to the script (using the Android Debug Bridge - adb) and do not need to recompile the app itself. It makes for a much faster development cycle.
