Ultra Mirage Nasal Mask Cushion Question

I recently acquired an Ultra Mirage Nasal Mask with a large cushion. It was in the lot I purchased and I was able to get a head gear that will work with it. I tried it briefly last night and the large cushion is way too big as I was leaking everywhere no matter how much shifting I did. I would like to replace the large cushion with the standard size cushion can I use this frame?

Does anyone want to trade a standard size cushion for the large? It appears to be brand new as it has no signs of wear whatsoever on it.
