Even though this is just a rumor I can see this happening, but first of all let's be clear on something.
When someone posts South Florida they may not necassarily be talking about a Miami-Ft. Lauderdale station. The Palm Beaches-Boca Raton market is also part of South Florida.
Perhaps X-102.3 may be doing well ratings-wise, but how is it performing revenue-wise?
We know that West Palm Beach doesnt have another FM Urban/Hip Hop station, and we also know that 102.3's signal reaches the entire West Palm Beach market unlike CHR/Pop outlet Wild 95.5. That is b/c Wild 95.5's signal is based closer to Ft. Pierce and as a result doesnt reach the Boca area very well. Boca Ration is a VERY wealthy area, and is a significant part of the West Palm Beach market (though at the same time almost every Miami-Ft. Lauderdale signal can easily be picked up in Boca.)
So, do I see X-102.3 going a bit more Pop but keeping its Rhythmic edge? Yes. I could easily see it moving towards a Now 92.3 New York sound.
