Two skimmers!?..........Sounds like a great idea to me, twice the oxygenation and double the export!
I run 2 skimmers in the same sump. If there were deleterious effects I wouldn't notice them because both skimmers consistently collect copious amounts of thick dark skimmate. I noticed the smaller one collected a little slower comparatively so I restricted the flow a little to compensate.
Two skimmers should not lessen the need for live rock.
