I would not do it. It is not the xbows that count so much in matchmaking, but the new archert tower, wizard tower, tesla and air defense.
As a 8.75 an average th9 can still 3 star you with most attack strategies like GoWi with backend loons, GoHo, or GoLaLoon. If you want to go this route, I would just place the 4th ad and have 2 good double bomb spots with the queen centered, so th8s will not be able to 3 star you any more. Mass hogs get killed by the queen, GoHo lacks the juice to get to the center at th8, dragons cant beat 4 ads and GoWiPe is not an option if you dont make an extreme wide open base or have golden walls. And against GoVaLo you can defend easily by spreading out the ads a bit, so they are not in the core. If they are in the middle ring, you should be OK because without queen there is no chance the wizards will get all of them.
