Palm OS

Has anyone successfully done this? my sister has an hp touchpad abd wants me to install android as a dual boot. after reading about it im honestly scared to do it. I consider myself a skilled rooter and rom installer, but i have only worked with android. never webos.

So i ask, it it easy? what are the options if I brick? how easy is it to brick and recover? I would like to get it done for her, but I dont want to break her stuff in the process.
