Mounting tie downs to top of TM for kayak.

I would appreciate your thoughts on this issue - mounting some type of tie downs on the top right ( as u r looking front to back) of my 2720. (opposite side of the door.)
My new TV does not have a luggage rack where I would normally strap my kayak to.
Weight I would think would not be an issue as one is spreading aprox. 40lbs over the entire front section. Wind resistance would pull on the tie down hooks etc. But a kayak is rather streamlined.
I'm not interested in adding a rack to my new TV.
But I am also rather hesitant to add holes to the top of the TM without understanding the consequences.

Thoughts?
Thanks.
