Specifically, abstracting over setting breakpoints and reformatting output is what makes that difficult. Everything can of course be done with enough effort, but especially in testing, it often makes sense to trade off duplication between test cases for ease of use.

Note that WinDbg (specifically) is an important use case, and uses a different debug engine than VS.  So Dexter would (at the very least) need to be extended to support WinDbg (which has the same debugging engine as cdb).  But I agree it's worth trying out and seeing what kind of test cases we can and can't fit into it.
