I like this idea, but would not fill the gutters. I would leave enough room for for the roof racks to be re installed.

I've had my ceiling out for the last 8 months seeking the source of the internal gutter leak. After seeing a pic posted here I and then doing a good inspection with a mirror and torch I'm 99.9999% sure the gutter profile looks very similar to the attached pic I drew. The gutter is one wide piece and the roof is welded to the middle of it so all you need is one tiny gap between inside and outside and a crack in the external sealant and you've got your leak. I'd previously sealed up all joints in the roof and around the alpine windows all to no avail but when I completely sealed the entire length of gutters with sikaflex 221 (which by the way thins in turps or metho, can't remember which) my leak from the gutter ceased. The leaks onto your feet from the faulty seal at the bend in the door and behind the dash are from a multitude of sources and for a variety of reasons which will take a lot of effort to fix. Good luck BTW in my diagram the vertical flange with the return on top also stops at the same position as the innermost flange (one on the right) so water can easily get to the innermost gutter; it doesn't have to flood over the top of the hooked vertical flange
