Redefine/alias a resource in WPF?

Question

Is there a way to redefine/alias an existing SolidColorBrush (or any other resource, actually)?

Case in point: I have a brush in an external ResourceDictionary that I want to reference by my own key instead of the original key. I don't want to be dependent on the external reference, since the actual brush is prone to change in the future.

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Window.Resources>
     <SolidColorBrush x:Key="SomeExternalResource">Red</SolidColorBrush>
    </Window.Resources>
    <Grid>
     <Grid.Resources>
      <StaticResourceExtension ResourceKey="SomeExternalResource" x:Key="SomeAliasedResource"/>
     </Grid.Resources>

     <Border Background="{StaticResource SomeAliasedResource}"/>
    </Grid>
</Window>

I don't want to be dependent on the external reference, since the actual brush is prone to change in the future.

You'll still be dependent on the external resource, just not in as many places.
