No. Please don't put script fonts in uppercase. It's absolute death to readability.
Actually don't put anything in uppercase - like underlining, it's a form of emphasis that has its origins in typewriters, which were locked to one typeface.
The uppercase letterforms are too similar -- there is no variation in the heights of the letters, so your eye finds it harder to read. Upper and lower case, you have letters like y and p and j which have descenders; b and d and t who have ascenders, and the variation is easier to parse.
For emphasis, please use size, weight, and italics.
