I've built several routings of 75K-80K miles. Some of those include a couple open-jaws though. I do have a LONE5 with no open jaws and ~78K miles and an awesome DONE4 (no Australia or Africa) with 75K and zero open jaws that originates in CMB. It does take advantage of some of the seasonal ANC flights you mention in NA though.
If you're trying to maximize miles on AA (like the majority of OW RTWers I think) Asia is a really difficult continent to include since JL doesn't give GLD/PLT/EXP bonus miles. I struggled with that and also forming an efficient LONEx since many of the OW airlines don't give 100% credit for L class.
