Reversed reverse tells, as part of an exploitative meta game strategy

I have been noticed more players looking for tells at the poker table as of late. As such, when I give off a tell indicating weak hand strength they react appropriately, calling with more marginal holdings.
However, against players with a better understanding of body language, who can spot the difference between a real and fake tell, you need to be a good actor. I'm a terrible actor
So the strategy I'm suggesting, is to deliberately act weak when you have a weak holding, so they assume it's a fake tell and therefore I must be strong. I would suggest using facial tells, as they are known as the least reliable... plus many times I have seen nitty players pulling a sour face then raising all in. Any opinions on this?
