From my experience, the on-walls produce a wider sound stage that may not require you to toe-in on them. I would just wait and see first. If you want to keep them wide spread and toed in, then the only recourse that I'm aware of is having to build something and mount them to that, but then you would probably lose the wide sound staging and bass boost from the lower ports by doing so.
