It's very unlikely BtB Sairaorg is faster than PDxD Issei, so he likely wouldn't be able to hit Yuuto. But on a similar vein, Yuuto's dragon slayers which allowed him to damage Issei will not be useful against Sairaorg, so he likely won't be able to damage Sairaorg with his attacks.

I would say it's a matter of whether Sairaorg can resist the life force drain of BtB long enough for Yuuto's stamina to run out, or conversely.
