No, the people that voted for Trump in this election will never vote for a non republican candidate regardless of how much you try to appease them. IMO you're more likely to lose even more voters than you stand to gain taking this approach. The democrats need to come up with a vision and candidate that is neither Harris, Biden, and certainly not anything close to Trump. They need someone that will make non-voters believe that there's a good chance their life will improve enough to make voting worthwhile.
