MMP is totally gerrymander proof and still allows voters to vote for the candidate of their choice in individual electorates (who may be from a different party than the one that they vote for).
MMP could easily be adapted in the US for presidential elections (maybe just voting for the national candidate instead of a candidate/party vote). If you didn't want faceless people from an electoral college making the final determination then you could always do what they do in France - hold a runoff election if no candidate gets an absolute majority of EC votes.
