Downloading DLL and assetbundle at run time in unity and start the game.

Hi, I have one unity project and have several games within it. So I create asset bundle of each game and delete all the game assets except for scripts so my project doesn't become big. when I play the game I download asset bundle from server and load it and boom game starts. Now I have created DLL of game scripts and deleted all scripts and tested it, game running perfectly. So what I am thinking is to keep this DLL and asset bundle on my server and download both at runtime and then to start the game. So is it possible to do it? I create build for both Android and IOS device. Will this approach work on both platform? Any help Please.
