timelapse raw file workflow - 16bit tiffs

[getho]

it just occurred to me that my workflow over the years is throwing away a bunch of data that could be handy. So rather than converting my nef raw files to highest quality jpeg, I exported to tiff. However: bridge>image processor> tiff only produces 8-bit tiffs.  

Does anyone know a way to batch create 16-bit tiffs, or other high bit depth format images that can be imported into premiere?

Searching around this topic, I've only found a bunch of noise.
