Stub Acme 2G and 4G

(OP)
I have a part where essentially we have two threads on the ID of one side of a part. The two threads are the same size and separated by a small thread relief. The only difference is, the Engineer wants to use a class 4G thread closest to the face and a class 2G thread after the first thread relief. Does anybody see this posing any issues during manufacturing or assembly? Can they be run during the same threading operation?
