Override or add some style properties in WPF - wpf

Question

I am porting a Bootstrap theme to WPF and faced a problem: I can't change some properties using additional style for StackPanel. I have ResourceDictionary containing BtnBase base style and BtnPrimary, BtnSecondary etc. All of them were inherited from BtnBase and contain only color properties. BtnBase does not contain any margin rule. When I try to add margin rule for a current StackPanel, there is no effect. I read about styles and knew that more than one style can't be applied, styles in ResourceDictionary have higher priority and I should use BasedOn. But I need to copy and paste my style in the StackPanel and replace BasedOn for each button variant. Is there a way to bypass it and add margin property for all styles?
code:
<StackPanel Orientation="Horizontal" Height="32">
<StackPanel.Resources>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource BtnBase}>
<Setter Property="Margin" Value="0,0,10,0"/>
</Style>
</StackPanel.Resources>
<Button Style="{DynamicResource BtnPrimary}" Content="Primary" />
<Button Style="{DynamicResource BtnSecondary}" Content="Secondary" />
<Button Style="{DynamicResource BtnSuccess}" Content="Success" />
<Button Style="{DynamicResource BtnInfo}" Content="Info" />
<Button Style="{DynamicResource BtnWarning}" Content="Warning" />
<Button Style="{DynamicResource BtnDanger}" Content="Danger" />
<Button Style="{DynamicResource BtnLight}" Content="Light" />
<Button Style="{DynamicResource BtnDark}" Content="Dark" />
</StackPanel>

You can treat all buttons as Items in ListBox.
ListBox will create a ListBoxItem for each Button, and you can add Margin to those ListBoxItems, using ItemContainerStyle. That doesn't modify Buttons styles, but creates same effect.
In ItemContainerStyle I also change ListBoxItem template to undo hover, selection colors, etc, which can change appearance - just plain ContentPresenter is left.
ItemsPanel by default is vertical StackPanel, but I changed ItemsPanel and layout to horizontal StackPanel.
<ListBox>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" Height="32"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Margin" Value="4"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<ContentPresenter/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
<Button Style="{DynamicResource BtnPrimary}" Content="Primary" />
<Button Style="{DynamicResource BtnSecondary}" Content="Secondary" />
<Button Style="{DynamicResource BtnSuccess}" Content="Success" />
<Button Style="{DynamicResource BtnInfo}" Content="Info" />
<Button Style="{DynamicResource BtnWarning}" Content="Warning" />
<Button Style="{DynamicResource BtnDanger}" Content="Danger" />
<Button Style="{DynamicResource BtnLight}" Content="Light" />
<Button Style="{DynamicResource BtnDark}" Content="Dark" />
</ListBox>
