Yes, it is possible but I see a couple of problems.
One, will you have enough room to fit a port light of any appreciable size? The cabin
roof slopes pretty dramatically over the v berth finding a port light to fit is going to be a trick.
Two Putting ports
in the side of the hull
so far forward just seems like you are begging for leaks
of Biblical proportions. If you have not yet dealt with leaks, you can not apprecciate how they can swallow up huge chunks of time trying to sort out.
Three, aesthetically it is going to look really odd. If you never plan on selling the boat then it probably won't matter but the shape of the other port lights is pretty distinctive. Putting in something that does not look like an after thought is going to be a tough call.
If it was me I would just invest in some really good quality cabin lighting
and go up on deck
when I needed more light. I don't know about you, but I use my v berth for sleeping and maximizing light is not exactly a priority.
