That depends on what you mean by "tweaking." You can use File > Place to put your AI files into an InDesign document, but they will not be editable there. Can you explain further what you need to do that can't be done in Illustrator at this point?
Ok I need to save AI docoumet as PDF and use InDesign Place command. AI doesn't support wrap text for Photos but InDesign does. That was what I wanted to tweak!
It's really not clear whether you understand your situation.

Or, you could just place the AI file, but in either case, when you do that, you'll essentially have a picture of your Illustrator layout on your InDesign page.

If you've already set all the type in Illustrator, you won't be able to re-flow it in InDesign. You can't Place a completed layout from Illustrator, then edit it in InDesign. To use any of inDesign's features, you'd have to rebuild the layout on the InDesign page; placing the images and/or vector graphics as discreet elements, and then setting the type in a separate operation.
