WMS servers like MapServer or GeoServer can do such reprojection, so you
don't have to modify your data. This has simply an impact on the WMS
performance. With vector data, it shouldn't be an issue. For raster data,
you can encounter some vizualization issue (since the swiss coordinate
system is "cylindrical oblique")

This piece of code is for the transformation of vector data. This is not
possible for raster data. I have seen in your code that you use WMS, so this
wouldn't apply. But, if you want to display vector data, then you can
reproject them on the fly with OpenLayers and present them together with
OSM. Be aware that OpenLayers can't represent a large amount of vector data,
for performance reason (particularly in IE)
