Tzlil,
I am a heavy ESRI user, and at this time I do not know of any way to accomplish what you are looking to do without converting to KML. But then again, maybe someone else might have a solution. If you find one please let me know. Also Tzlil your English is great.
Also quick tip, you can publish / convert Toolbox --> conversion tools, --> map to KML, which can drastically cut down on converting instead of using Layer to KML
Good luck.
