One option is having no headboard.

I like it as it is

If you use long drapes/curtains/sheers on the windows, I think you could easily put the bed under it with the existing headboard. Is there a reason you don't like it where it is?

I do t like where it is because when u walk into the room I like the bed facing out. Let me know!

I have a large 4 poster bed with a pretty massive headboard in a relatively small bedroom. I have the bed under a single window and have used the window treatment as a "canopy" for the bed. Most designers would probably be horrified at the idea but I love it. And that's the real issue after all right? Put it where it makes you happy. I see you have shutters on the windows. Obviously, you will render those useless if the bed is higher than the bottom of the window so I would switch those out and use curtains. A sheer or lighter weight fabric, maybe even something as simple as muslin, would cover the windows while still allowing light in and maintaining the beachy feel. I would probably put the bed under the double windows. You could either bring the fabric all the way to the corner on both walls or just put it around the windows themselves. Hope this helps and keeps us posted. :)
