It's probably simpler to build that composite simulation box from 
scratch. Use editconf to do the translation/rotation of your solutes, 
then do the copy-paste on the coordinate file, then generate solvent, 
then copy-paste the .top together suitably, adjusting molecule counts 

There's no tools to make easy your task as described, because it's not 
something you'd really want to do often.
