#DrawDebugHelpers.h
If you just want to draw a wire sphere you can do that right now, without direct access to PDI, using the DrawDebug version!
/** Draw a debug sphere */
ENGINE_API void DrawDebugSphere(const UWorld* InWorld, FVector const& Center, float Radius, int32 Segments, FColor const& Color, bool bPersistentLines = false, float LifeTime=-1.f, uint8 DepthPriority = 0);
You just type the function directly, it is ENGINE_API

#Drawing to PDI
I explain how I got access to the PDI (After many hours of hunting) here;
I am quite curious if there is some easier way, my only solution was to actually make UPrimitiveComponent and draw to its PDI
