Hi Jk Sung,

Yes, this is possible. With our latest official release (Telerik UI for WPF Q1 2016), we made it possible to use the series provider and create any series, including range bar series, without using specific series descriptor. Basically, you can define a ChartSeriesDescriptor and create a custom style whose TargetType is set to :RangeBarSeries. 

<telerik:RadCartesianChart.SeriesProvider>
  <telerik:ChartSeriesProvider Source="{Binding Data}">                  

<telerik:ChartSeriesProvider.SeriesDescriptors>

 <telerik:ChartSeriesDescriptor ItemsSourcePath="SaleInfoData">

   <telerik:ChartSeriesDescriptor.Style>

     <Style TargetType="telerik:RangeBarSeries">                                  <Setter Property="LowBinding" Value="LowValue"/>

       <Setter Property="HighBinding" Value="HighValue"/>

       <Setter Property="CategoryBinding" Value="MonthName"/>

    </Style>

   </telerik:ChartSeriesDescriptor.Style>                             </telerik:ChartSeriesDescriptor>

 </telerik:ChartSeriesProvider.SeriesDescriptors>

</telerik:ChartSeriesProvider>

</telerik:RadCartesianChart.SeriesProvider>

For your convenience, we have created a sample project where you can see how to implement this approach

Hope this information is useful.
