Yes, absolutely — you can run multiple Vanguard heroes on a single Marvel Rivals team, and there are no hard rules preventing you from stacking as many tanks as you like. In fact, double-Vanguard compositions are not only viable but are widely used at multiple skill levels, from casual matches to high-level competitive play. The real question is not whether you *can* run multiple Vanguards, but rather *when* and *how* you should do it effectively.
