UnreaEngine 2.5 L2 Lighting To Unreal Engine 4.0

Hello, there is a game Lineage 2 (UE2.5) , i like alot lighthing/render in it, they made it very custom and adjustable in different values - their settings.file (were u can see how many things it could tweek) .

I even decompiled this ligthing/render parts, to see how it affects environment(terrain,buildings,trees, meshes, etc)

So i was wondering is it relevant to use ue2.5 lighting(parts) in ue4.0, or its enough to hire an compatible visual designer/artist, who would be able to tweek settings, so the lighting(in ue4.0) would match the one in lineage 2 !

Thanks in advantage !
