You man Nelson, Napoleon and his marshalls and Wellington are on the same side?
They win any battle. However, they don't have the manpower to garrison the world. So any takeover would have to be gradual.
Actually - if the other continental powers act together as they did in OTL from summer 1813, then France and her sailor ally are as doomed as France and whoever allies France had in 1813 was.
On the really grand lines the Napoleonic wars initially was France taking on the continental enemies one at a time and (therefore) defeating them. Once the continental powers got their act together that ended - and France was defeated and would be in most scenarios.
Adding the British Army to the French is a bad substitute for the OTL huge contribution from the German states - who now belong to the "world" uniting against the Anglo-French.
The RN can cruise as much as it will on the seven seas, it won't influence things on the continental battlefields.
