Yes, that's been done, I'm actually aware of at least two groups who did 
it, and I'm sure there must be several others.

Since the S52 symbology is a standard, it would make sense to open 
source those mapfiles to improve on them collaboratively, but 
unfortunately none of the groups that I am aware of were able to open 
source their configs so far.

A few hints:

- Convert the S57 data to shapefiles or postgis to make your life easier
- Most symbology can be handled directly in mapfiles, except complex 
symbols such as light houses that require some pre-processing to 
generate new shapes for MapServer to render (showing the radius/range of 
the light house)
- Check out OpenCPN if you need some inspiration, especially 
https://github.com/OpenCPN/OpenCPN/tree/master/data/s57data
- If you want to overlay multiple layers of S57 data in the same map, 
then you may need this MapServer 7.0 enhancement:

Good luck
