Yes, it is possible to do that in EnergyPlus. If the merged ceiling surface will be a rectangular surface, then in idf, two vertices of first and two vertices of fourth split surface (in BuildingSurface:Detailed object) can be used to create the merged surface. Once a new BuildingSurface:Detailed object for merged surface is created, all the 4 split surfaces should be deleted.
