There’s a Blueprint node called ‘ExportTexture2D’ that will export 16-bit assets as a .hdr image, which Photoshop and many other image editors can open. You can use that as a workaround to export 16-bit images, though the .hdr file format doesn’t support alpha. I don’t think that matters, as it looks like the Paragon assets mostly use separate mask images rather than alpha to store transparency data.
