Yes you can use the DAC export import functions to migrate execution plans - but i dont think you can be selective. However my recommendation is to export none of them. I would export then import only the subject areas etc. from the tab "Design" which is metadata category "Logical" (do not export the execution plans which is metadata category "Run Time" ) - then on the target environment re-build the execution plans based on the updated designs after import. It only takes a few clicks to build the execution plan.
Not sure what version you are on but details in the user guide.
