Are two Southerners (like Andy Beshear and Raphael Warnock) what the Dems need to secure a victory in 2028?

Democrats are electable in the South at a state level, examples include Edwards in LA, Beshear in KY, and Warnock + Ossoff in GA. But in the 2028 presidential election, should the Democratic Party go the Bill Clinton route and elect two moderate Southerners to gain appeal in swing states like GA, NC and AZ, and possibly flip another state or two?
