I know this is old but apparently, suggestions are still needed. Here is what I did:
I set the radio button font to a fixed-width font.
Took the longest word and set all radios buttons to that letter count
I used a code so that I could get numerical values from the radio buttons later.

I then set the Font color, hover color, pressed color all to transparent.
I then used labels and placed them where needed for the correct text of the radio.
I set the Reorder on each label so that its alignment was all the way to the back this way you don't have to click on the radio itself for it to select.
