Well, this depends on what you're trying to get out of the whole thing. I think that from a recovery point of view that you may be overloading a bit, but that's going to depend on how hard you roll, what you do for conditioning, and what day of 5/3/1 you're on. There are ways to structure your training where the off days you'll get as a result of this schedule outweigh the tradeoffs you'll have to make to keep from getting hurt.
From a technique point of view, when you're exhausted you have to focus more on technique to get things right, but your muscle memory builds faster. My training was based around pre-exhausting muscles before learning technique, and it gives me confidence to know that I can execute my full range of techniques effectively when I can barely lift my arms. YMMV.
