Ahh no sorry, there are two challenges that you would have too overcome, the first being the hardware aspect. The tegra 3 SoC isn't just a CPU but APU that has both a CPU and GPU on the same chip. This chip is physically soldered to the motherboard. While its not inconceivable that a very skilled person might be able to remove the chip and replace it with an identical chip (in theory).
You cant replace the tegra chip with another for both hardware and software incompatibilites, our phones whole motherboard is designed around the tegra3 and its very intricate details of operation. But let's pretend the hardware will be compatible and a exynos octa core is what we will use, the next problem is software. The kernel is the core of an operating system, on the arm platform the Linux kernel is different to that of x86 based devices, arm devices need extremely specific kernel support, you would in essence have to rewrite or re engineer an entire devices specific hardware support in the kernel, for scale the difference between mainline 3.1 and the 3.1 android kernel in our device is about a million lines of code, I'd guess lge's changes would be around 50,000 lines of code for our device.
But I somehow don't think its worth it
