Sure you can (see e.g. V4L1 API), it is just very, very painful and takes
a very, very long time.

I wasn't planning on removing anything.

Although I might deprecate the old API eventually in ivtv. But apps like VLC
and MythTV use it in their ivtv code, so I can't do that until they are all
converted. So we're talking 2-3 years from now at the earliest. I'm not even
sure if it is worth the effort.
