Default [Q] TRACPHONES and Cyanogen Mod

Hi I have been checking out Tracphones and I was wondering if the prepaid Tracphones would be able to be modded with the Cyanogen Mod. If they are able to be modded please let me know Thanks. Here are some of the models available at Tracphone

LG Optimus Dynamic 2 + Android
LG Optimus Dynamic + Android
ZTE Valet + Android
Samsung Galaxy Centura + Android

I cant seem to find any of these phones here on the forum.
Thanks again.
