There are a number of options here:
1) Completely replace CampMM with BK
2) Move CampMM up the road to the cast member bridge, and put BK where CampMM sits now
3) Remove / relocate that water container (resevoir?) and put BK at the end of the cast member bridge
4) Build a new bridge over by Harambe and build BK next to Harambe.
5) Build BK behind the Rainforest Cafe / Oasis / CampMM area
I think that options 1 and 3 are the most realistic (the other optionswould require much more work), but any of them could work.
