My 44-2 is definitely swirlier than the 44M-4. You won't need to reverse the front element. But if you do.....here are two examples from my Helios 44 zebra (same design as the 44-2) with the front element reversed - quite an easy modification, and easy to reverse again to the right way round.
It may look like mush to some, and needs some aggressive processing, but it produces some fascinating light effects. Plus a few flying fairies in the first!
BTW of all the lenses I've tried reversing, the Auto-Takumar 35/2.3 produces the best combination of sharpness and swirls, but that's another story.
