Use Boost unit test framework for regression testing

I use the boost unit test framework to test a codebase. I want to add some regression testing. I am considering a shortcut which would be to use the unit test framework, add a "regression_test_suite" test suite, and implements my regression tests there. That would save me from having to manage another test framework.

Is it acceptable, or I am in danger of regretting badly that decision down the road? Or maybe missing on some really critical feature by not using directly a proper regression testing framework?
