Convert Trumpeter 1/350 USS Langley to USS Jupiter

I have 2 Trumpeter 1/350 USS Langley aircraft carriers. I became interested in the Langley as being the first American aircraft carrier. I then found out it was originally a barge called the USS Jupiter. I would like to build 1 kit as the Langley, the other as the original Jupiter, but have so far found no such conversion kits, even as 3d printables. Does anyone know of any such conversion kits?

Welcome to the forums GameGuru. I can’t help other than to suggest scratch building. Here’s a link to the Jupiter’s general layout blueprint which may help in your endeavor.
