Ok I am not sure how to ask this question so I will explain exactly what I want to do and why I'd like to do it if possible. I have an iReadyGo Much G2 android phone and it is running Android 4.2 but I really want an Android Wear watch which requires 4.3. I don't expect this phone to receive an update anytime soon so I want to know if it would be possible to develop a ROM to bring this phone up to speed and put Android 4.3 on it.

Sure. You can write a ROM to match any Android version and you can write a ROM to run on any hardware (look at Android-x86 - they have 4.4 running on a desktop). All you need is the knowledge and experience to write the code. (If you were thinking of someone else doing it for you, expect to pay a couple of hundred dollars an hour for about 6-12 months of 40 hour weeks.)
