Wondering if I could partially close a 2 to 2.5 mm gap in front teeth with direct bonding until I can afford veneers? (photos)

I am not a good candidate for braces, I have been told this by several orthodontists. I would really like to a least partially close the space in my front teeth. I was curious if I could do this with direct bonding until I can afford to get veneers. I understand that if I was to get the space fully closed, my teeth would appear wide. I just want some kind of fix until I can get veneers.
