Since you said you're a big mountain comp skier i'm gonna assume you prefer to ski fast and go big. IMO I think your current setup will suffice, but won't be optimal. I'm 5'10 and my pow/freeside skis are 188 and 116 underfoot and personally I wouldn't go any shorter. They float super well in pow and are very stable when skiing fast or going big. I've tried shorter skis and they start to feel sketchy when I'm skiing fast or when I'm in deep snow.
If I were in your situation I would try to get some longer skis, but if you don't want to go through the hassle of selling them I think you will still be fine.
