As I mentioned, you can do it with Tempest (the library). You can have your own test suite that does exactly what you are asking (namely, a set of scenario tests based on Heat which targets the TripleO use case) in a Tempest plugin and there is no absolute reason that those tests should add 5-10 minutes of runtime compared to pingtest. 

It/they would be exactly pingtest, only implemented using a different library and running with a different runner, with the *exact* same run time. 

Obvious advantages: only one technology used to run tests, so if anyone else want to run additional tests, there is no need to maintain two code paths; reuse on a big and proven library of test and test runner tools.
