Yup, setting up the CalDAV server itself is not a terribly large job,
but I'd expect modifying IC/VC to support CalDAV would be a few months
work. I've not looked at the CalDAV protocol, but I have managed a
CalDAV server at a fairly low level, it's HTTP based with one iCal/ICS
file per calendar event.

IC/VC imports a single iCal/ICS file (or list of single files) with
multiple events, but I don't recall what sort of duplicate checking it
does. It does support exporting individual or multiple events as
iCal/ICS files. So, it'd have to be modified to not only support
WebDAV (the HTTP-based file protocol for reading/writing the
individual files), but also to detect changes, compare individual
events, and change events. There are also a number of fields that it
doesn't support or deal well with, that might need adding support for
in order to make it compatible.

So, there's a good, solid base to build on, but there's a lot of
complex functionality that'd need to be added. Eckhart can probably
give a better answer as to whether building on top of IC/VC or a new
implementation would be better.
