No, it's not possible to install Android on an LG Voyager, any more than you can install an iPhone OS onto a Voyager. The reason you can't do this is because the hardware is not supported, and LG won't have written the device drivers and other low-level code for Android.
I can't go into any more detail than that, as it won't make sense if you're not a software developer. Suffice to say that if you've asked the question in the first place, then you're probably not going to understand why it's not possible.
If you want an Android phone, buy an Android phone.
