It's possible. Added a `PassManager(StringRef Name, StringRef Pipeline, CreatePassFunc CreatePass)` constructor to `PassManager` and similar ones to `FunctionPassManager` and `RegionPassManager`. Now both RegionsFromMetadata and BottomUpVec initialize the pipeline using the new RPM constructor

What's the advantage you see in doing so?
