I thought about this because I can smell a faint whiff of egg from RI which puts me off it a bit (weird I know – not sure if lemon juice would help this)… The main issue I have is the chocolate would keep solidifying as you worked with it which would make piping a real pain (especially removing metal nozzles or squeezing it all out to reheat in the microwave). You could probably do a brush/ painting technique more easily… If you try I would love to see the result
