Religious folks, especially Buddhists and Hindus! Is this a good or bad idea for tattooing myself? ?

I like the idea above me about trying to combine all of them. IN my opinion their is nothing wrong with what you want to do although, it sounds like you are rushing into this just because you want some more tats which would be a mistake. As for the questiion to the muslims i say fu--ck what the muslims think if a certain muslim symbol means something to you get a tat of it whereever you want.
