It's a good idea too.
I have found another very interesting plugin to follow test results : test results analyzer. It works with result published by xunit.
I think the three plugin are really complementary :
- xunit plugin allow to managed many report of test tools and compute the build result according to threshold,
- test-stability plugin add information on the stability of the tests,
- test result plugin allow to see in one page which tests failed and in which build number
