我是否可以为WPF ComboBox中的选定项使用与下拉部件中的项不同的模板？

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <!-- 下拉列表项模板 -->
        <DataTemplate x:Key="DropdownItemTemplate">
            <StackPanel Orientation="Horizontal">
                <Image Source="{Binding ImagePath}" Width="20" Height="20"/>
                <TextBlock Text="{Binding Name}" Margin="5,0,0,0"/>
            </StackPanel>
        </DataTemplate>

        <!-- 选定项模板 -->
        <DataTemplate x:Key="SelectedItemTemplate">
            <StackPanel Orientation="Horizontal">
                <Image Source="{Binding ImagePath}" Width="20" Height="20"/>
                <TextBlock Text="{Binding Name}" FontSize="16" FontWeight="Bold" Margin="5,0,0,0"/>
            </StackPanel>
        </DataTemplate>
    </Window.Resources>

    <Grid>
        <ComboBox x:Name="MyComboBox"
                  ItemTemplate="{StaticResource DropdownItemTemplate}"
                  SelectedItemTemplate="{StaticResource SelectedItemTemplate}">
            <ComboBox.ItemsSource>
                <CompositeCollection>
                    <CollectionContainer Collection="{Binding Items}"/>
                </CompositeCollection>
            </ComboBox.ItemsSource>
        </ComboBox>
    </Grid>
</Window>

public partial class MainWindow : Window
{
    public ObservableCollection<Item> Items { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        DataContext = this;
        Items = new ObservableCollection<Item>
        {
            new Item { Name = "Item1", ImagePath = "path_to_image1.png" },
            new Item { Name = "Item2", ImagePath = "path_to_image2.png" }
        };
    }
}

public class Item
{
    public string Name { get; set; }
    public string ImagePath { get; set; }
}
