I don't think the schedule is aggressive enough for a 2020 Mars launch with the Starship. It is likely that Starship will be capable by then, but the wow factor is missing. I don't think an interesting mission would be ready. Don't forget that Musk's Tesla was already launched to "Mars". So it would be safer and just as impactful to have an interesting mission planned using Falcon Heavy. The only mission I can think of which might be viable is Starship landing on Mars. However I don't think SpaceX would have proven Starship enough to get approval for that.
