Greetings from New York!
Thanks for inviting me over DXMeister!

And just in time too! So I'll say my answer.....
YES and I WON'T get over it (sorry, not my job.) But the YES answer can't just stand there without giving an explanation regarding my thoughts on Los Angeles and dance music on the radio there. And to that, I'm admittedly hesitant with the term "true dance".
I have visited Los Angeles and have heard Mars and Groove Radio on 103.1. And while I do feel that Swedish Egil is very knowledgable in terms of dance music, the sounds that came out of there may have been WAY ahead of its time. Granted, for a core fan such as myself, I LOVED what he did there. But then again, there are more casual fans than core and while Mars & Groove certainly had a cutting edge sound to it...the casual fans still were lost in the loop of things.
For a "rhythmic" station (note that I am NOT saying pure dance here) to work for Los Angeles, it has to be a current leaning version of what KPWR (Power 106) was back in the 80's.....to compare it to today, like Pulse 87 is now in New York
http://www.pulse87.com, with the currents, but also with that regional flair of dance music that can perhaps only be "L.A." and cater well to that audience. I didn't state "true" with this because unfortunately, dance music as a whole isn't a strong enough genre in this country to maintain it's own presence without any other genre thrown in there.....
YET! So to that, you have to mix in some pop-remixes, some R&B, a small miniscule "dose" of hip-hop (the fun loving, party stuff..aka Flo Rida, not the gangsta elements). But at least have 70 percent of the format with current dance...and a classic/recurrent thrown here and there.
You do have the Chicano population, gay population, many transplants to the region from other areas that would be into it. It can sound as good as Groove Radio but in the process not alienate the casual fan from the core. And you have to get to the Latinos. THAT is what will make a rhythmic station in the Los Angeles/Orange County area work.
