Hi Eric, Yes, you can transcode them on the fly with a server like https://github.com/developmentseed/titiler. I haven't used that one, but wrote a prototype of something like that in the past.
You might want to have the original in EPSG:3857, though, to avoid the need to reproject the tiles when loading them, but doing it on-the-fly is also possible in theory.
