WPF Flat Repeat Button (ToolBar look)

Question

I'm trying to give the RepeatButton the flat look w/o overriding the ControlTemplate. With the regular Button you can do the following (but not with the RepeatButton):

<Button BorderThickness="0" Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}">...

Is there something similar for the RepeatButton or for ButtonBase? I'm assuming no because if you put a RepeatButton in a ToolBar is does not get a flat look.

Is there a better way to give the RepeatButton a flat look other than overriding the ControlTemplate?

Here's what came up with for a flat RepeatButton Style with a Path as content:

<Style x:Key="RepeatButtonFlat" TargetType="{x:Type RepeatButton}">
    <Setter Property="OverridesDefaultStyle" Value="true"/>
    <Setter Property="Focusable" Value="false"/>
    <Setter Property="IsTabStop" Value="false"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type RepeatButton}">
                <Border Background="Transparent" Height="14" Width="14">
                    <Path HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Uniform" Margin="2"
                          Data="{Binding Path=Content, RelativeSource={RelativeSource TemplatedParent}}" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Sample usage:

<RepeatButton Style="{StaticResource ScrollBarLineButton}" Content="M0,0 L1,0 .5,-.5 Z"/>
