You should also remember that gasper has also been drinking issei's blood for over a year(both before and after he got his new body; which kinda of makes me think that later down the line gasper's sacred gear did get some of it divinity back due to issei's god power, but not to the point where gasper could be considered a god(like how earlier on how issei was considered a dragon due to his sacred gear), but maybe he could be considered a demigod; opinions on this?) and that rias, along with akeno has been siphoning off his dragon energy(both before and after he got his new body), so i think it's more than possible that rias and gasper can take on an 80% fenrir.
