Which one? BoardGameArena has quite a bit of them already (to name's a few: Carcasonne, Terra Mystica, 7 Wonders, Seasons, Race for the Galaxy, Through the Ages, Puerto Rico) and they have nearly 100 more licenses available over BGA Studio that still require developers to make (here's a few: The Castles of Burgundy, Galaxy Trucker, For Sale, Santorini, Myrmes).

I don't know how they acquire theses licenses, but if they did, maybe you can too and if you can't, maybe they already have it made, or needs a developer to implement it (which can be you!).
