I might be wrong, but I think that would not be easy to pull off in the existing base test framework. I think it would probably be much easier to add debugging support to the test item framework, in fact pretty much all the pieces need to pull that off inside VS Code exist already. I “just” need to hook it all up No promise on when that is going to happen, it is on my roadmap, but it also is probably a pretty significant lift, so it might be a while. But at least the design should really lend itself very well to implementing this.
