Understanding that Illustrator has some principally different kinds of elements that InDesign, I believe it's possible at least export some simple things with a warning that anything complicated will not be saved (as it happens when exporting to some kind of eps10 for example). Should be kept: general arrangement of elements, text, illustrations from simple forms (without meshes, ets). Illustrations made by fundamentally different methods can be offered to rasterize during export, blends and similar could be offered to expand.
