Why don't you use a stackpanel wrapping a couple of textblocks instead? Then adjust the margines on the stuff you want super and subscripted.

        <StackPanel Orientation="Vertical">
        <TextBlock Text="H2O3" FontSize="40" Margin="0,10"/>
        <StackPanel Orientation="Horizontal">
            <TextBlock Text="H" FontSize="40" />
            <TextBlock Text="2" FontSize="40" Margin="0,-20,0,0"/>
            <TextBlock Text="O" FontSize="40"/>
            <TextBlock Text="3" FontSize="40" Margin="0,10,0,-10"/>
        </StackPanel>
    </StackPanel>

There's an alternative but it's only available in WP8: Typography.Variants.

I personally prefer this approach as it aligns more with WPF but there are cases where you have to do baseline manipulation or in this instance, margin wrangling. If WPF is any indication, it also requires a font that supports variants which are generally open type/true type only. See Superscript / subscript in hyperlink in WPF for a better explanation.
