I don't think that necessarily solves the problem. You might end up with a state where congresspeople are geographically close to their constituents but non-representative in a number of other ways. For example, (arguably) representatives' political affiliations should roughly correspond to the affiliations of the state's voters — so if you had a state with 4m Democrats, 4m Republicans and 2m independents out of 10m voters total, you might have 4 Republican, 4 Democrat and 2 independent majority districts. There are undoubtedly other factors to consider than proximity and party affiliation. The key takeaway is that districting is an opinionated act, algorithm or not. If we're going to "solve" gerrymandering, we need to figure out what "successful" districts look like first.
