I'm not sure whether it is possible to install another office trial over another - what I've read online seems to suggest that there is a mechanism in place to prevent this as the intent is "if you want it, you will have to buy it" following the 30-day trial period.
Having said that, some people have identified some methods to accomplish what it is you are after, even going as far as reformatting and then reinstalling - Problem installing Office 2010
Hope this helps in some way
