I know it is a goofy routing BUT if you are in for a dime you are in for a dollar. Why not MSP-LAX-MIA-MCO on AA? LAX-MIA has frequent 777's - now that is a first class aircraft!! You can book business and the hard product will be far better than anything you listed above. The 77W's are true 3 cabin and will have international F. Just my $0.02
