Thank you all folks for the support.
Recluse and myself have in fact talk about integrating his map into mine (or the other way around). However, his map is based on the in-game map and for me to easily integrate it with mapbox engine it needs to be georeferenced. I have done it, and the result is not as nice as I would like it to. Afterall I am a GIS aficionado and not as experienced as Domox (he also uses Mapbox but I believe he made his map from scratch), so I am sure it should be possible to do it perfectly with a bit more experience.
For those curious, here is the result after georeferencing (only the map layer is shown): http://naval-action.byethost7.com/recluse/
You can really appreciate the distortion when zoomed all the way out.
By the way, it is not being maintained, so please do not use it and keep relying on Recluse's map.
