The Greek Ano Teleia (U+0387) looks decent with some fonts:

Here's an example of what it would look like in your particular case (all of the superscript characters are Unicode characters):

In this example it looks really good, but in other fonts, the character hovers closer to the middle (vertically) of the superscript characters.

Even in fonts that it does look good with, if you increase the font-size enough, it becomes apparent that the dot is not quite where it needs to be.

I really wish that an official superscript/subscript decimal point would be added to the Unicode standard as all of the characters that can be used to substitute these characters are font (and sometimes size) dependent, so there's no guarantee that they'll look good in all use-cases.
