Big baby swaddle

My boy is 3 months and was an average birth weight but has been huge ever since. I estimate he is about 18lbs and 23-24 inches. We’ve been using halo swaddles. Both the sleepsack swaddle and the swaddle sure. We’ve also been fading them because he’s rolled belly to back very early. First time at 6 weeks but only a few times since then. I think his weight is holding him back.

Anyway, he’s had one arm out of the swaddle fur weeks, but isn’t ready to have both out yet. I’ve tried a few times and he wakes a ton from his startle reflex, which is still present but hopefully starting to fade.

He’s become too big for the swaddles we have but I’m not comfortable going cold turkey yet and Halo doesn’t have a bigger size.

Any recommendations?? Thanks!
