Sounding like someone isn't just having the same timbre of voice, it's cadence, accent, diction (both definitions). I'm skeptical how much two unrelated people could just happen to sound alike, especially if one of them is famous for their voice. Compare Larry David's natural speaking voice to how he speaks when impersonating Bernie Sanders. Those are two men from the same time and place and background, and there's still quite a gulf. Now perhaps you could just happen to sound like a famous actor who isn't well known for their voice, like John krasinski or something, who does voice over ads but isn't super distinct. That would probably be fine but you're still going to have to slog through the world of voice talent auditions
