Quick compile for android or swapping asset files without rebuilding`?

Is any of the above possible?

I’m doing some test runs on Android, one of them consists of swapping between several different wizard models to compare frame rate and other things.

Everything else equal, all I’m changing is the model file that is being loaded with assetmanager in one place in the code.
But I need to rebuild and compile, transfer to my phone, which takes 2-3 minutes each time.

I’m thinking it might be possible to do some kind of fast recompile when only 1 code file is affected, or even open the .apk / .jar on my phone directly and swap the model .j3o files.

Would this be possible?
