What are Potential Problems of Using Another Filler on Top of Silikon 1000?

Hi. I am contemplating Silikon 1000 and am very interested in a natural look, so the following is unlikely to happen, but I'm curious about it: If one got a small amount of Silikon 1000 in, say, the lips, and chose to instead use a different (temporary) filler on top of it, what would the end result be? Is that dangerous? Last time I tried to ask a question here re Silikon the only answer I got was from a physician saying basically that Silikon 1000 is the devil, so just a serious answer, please
