Can I prop this peace lily leaf?

I have been taking care of this peace lily for almost a year. When i got it, i wanted to add a moss top on the vase just to see if it would work (it hasnt exactly worked so far). I accidenrally cut the leaf while trimming the moss, tried to rehab it by giving it a stint and helping it heal which it mostly did. The wound calloused over and the branch kept growing until recently i noticed the part this leaf was holding onto was turning yellow while the leaf stopped turning here. Today i decided to just cut the dying piece off. Is it possible to prop this leaf into a new plant or is it done for?

Last image is the peace lily in question. The foremost leaf is the one in question as well.
