Probably only one day for one skilled craftsmen...not a gargantuan
job.

I suspect you will not be happy with anything that repairs what is
there. You might get some help by staining and some grinding, but the
results are not going to look really good. The idea of topcoating is not
wise in my opinion as the color and finish is not likely to match what you
have and it may not be structurally sound and flak off.
