Call me crazy... android?

[SrgWallopy]

So i've had this idea that the android rom for the ally could easily be manipulated to run on the fathom. Since they are obviously made by lg and look almost the exact same, i would think that the hardware on the inside would be fairly similar as well.
Besides the screen, and the processor i see nothing else that is "totally" different. Oh, and the Dual band gsm/cdma for the fathom.

Pic attached is a picture of them side by side.
Thoughts?
