I'm shooting off of memory here, I've only seen one G5 sight, but the pin housing itself could be flipped over, giving like.......3 more inches I believe......If you've already done that......Have you tuned your bow since changing to carbon?? Carbon is smaller diameter, and a rest adjustment may be needed.....Also, if you raiseyour anchor (ksser and/or peep) it will raise your point of impact a bit.....That may or may not be an option for you though...
