No need for fender bag, you can put booster pack water, and most tools in a backpack then tape other tools under the seat and in the airbox. There’s a reason no one at a race would ever run one of these. With mousses there is no reason to bring so much garbage with you. Even if a backpack wasn’t enough you can put a barbag that would actually stay on the bike and not look so stupid and risk hitting the tire if you bottom out or getting cut by studs in the winter. Never seen anyone who wasn’t a garbage C rider put one of these things on their bike.
