Merlin suit / sleep sack transition

Is the Merlin Suit worth transitioning off of it later on? My 10 week old is showing signs of rolling (up on his side) in his swaddle. So I have tried the sleep sack that has the arms up so he has access to them and his sleep at night has gotten worse. I have resorted to bringing him into bed with me using the safe sleep 7, but I ideally do not want to cosleep. But I also want to bite the bullet if weaning off the Merlin suit is hard too.

Thoughts anyone?
