Darkstrider as Re'Vas buff in Raids

Basically title. Do you think putting some upgrades into darkstrider as an Addition buff for Re'vas is worthwhile? For context: im playing a (for the moment) Budget multihit comp and since Chaddius cant be used for Rogal Dorn i was wondering if the Markerlight from Darkstrider could be a nice replacement. Especially considering i could just apply it via the Tau MoW. Any insight appreciated. Cheers

Edit: Yes i know the Tau MoW exists. Yes I own it. Please consider reading the full Post :/
