Then OpenIV team have been working on a tool that will allow you to port the map of Liberty City from GTA IV to V for a few months now. This past week they released a few new screenshots to tease the new project.
The new screenshots show off two areas not previously seen in the mod, in the Broker Bridge and Algonquin areas of the city, as well as a building interior, and a new shot of the city landscape.
Once the mod is released, you will need to own GTA IV and V for it to work, as the mod copies the required assets from IV to V, meaning you need to own copies of both games. It does work with the Liberty City DLC however.
