Aren't 120V sources from breakers just all in parallel behind the breakers? If you've got isolation transformers or other seperate AC sources then that's fine, but trying to connect two parallel voltage sources in series to add the voltage just ends up shorting two contacts. And you need to make sure that the two AC sources are in phase. Ideally the AC coming out of a transformer would be in phase with the input, but in reality there is a shift and it can be as high as 30°. So either adding waveforms from two separate isolation transformers or two inverters with a shared 60Hz clock would be about the only way I could see to get it to work. You shouldn't have any problems with the 50Hz/60Hz inconsistency.
