Sure...I'm going to buy $7/qt Royal Purple and put it into a 100,000 mile engine and then report back to you just to prove something I already know.... Or were you foolish enough to actually buy $40 worth of Royal Purple and put it into a worn out engine?
Throwing transmission fluid into the crankcase is a little different than trying a different oil....don't you think? Either way, anything ready to "come loose" will do so without worrying about what type of oil your running through the engine, regardless of the amount of detergent. Heat, pressure and thermal expansion have a little more persuasion in breaking things loose than your oil will.
