XAML, move two contentcontrol inside a button with animation

Is it possible to move two contentcontrol inside a button and also resize this said button?

<Button Height="100" Width="100">
  <Grid>
    <Grid.RowDefinitions>
       <RowDefinition height="30"/>
       <RowDefinition height="30"/>
    </Grid.RowDefinitions>
    <Image Grid.Row="0" Source="img.jpg"/>
    <TextBlock Grid.Row="1" Text="Some content"/>
  </Grid>
</Button>

I would like to align them horizontally instead of vertically on MouseOver and resize the button from 100 to 50, is this possible ?
