Just my opinion here but I think this is a bad idea. You'd have to research to make sure that your hack isn't also artificially inflating the number of pageviews, increasing the pages / visit and artificially deflating the Avg Visit Duration. By screwing with one metric, you're probably affecting several others.

Better to just leave it as is and do a better job interpreting the data. If you run a blog, you're simply going to have a high bounce rate. But as long as your avg visit time is still high, you can interpret the data in a positive way and effectively ignore the bounces.
