Option to set widget length

Would it be possible to add an option to set a widget's length? Possibly with a further option of either justifying or centering the text.
Mainly want it for the sake of Now Playing or similar widgets which are constantly changing length. For example: Now Playing scripts can be limited to a set number of characters to keep them from being too long, but there's no way to keep the widgets from becoming really short if the song/artist names are short.
