No, because the high potency stuff merely increases THC but does not increase and in fact often decreases other psychoactive compounds like CBD. It will not be the same.
I had nothing scientific to go one, but have long felt that mixing 50/50 with CBD specific flower may be putting it a lot closer to the old school stuff.
Looking at a couple of the studies linked to from the comments, seems like that broadly about right.
(Hypothetically, if I was a Marijuana user) I (would) exclusively use edibles for this exact reason. Dosage is labeled on individually wrapped pieces with the exact amount of thc/cbd/cbg/cbgb on the packaging
