You might have a problem in that some teeth in the outer chainring are designed to be shorter to assist in upshifting. With an extreme chainline (when at biggest sprocket for example) this could result in the chain de-shipping. I'd advise to look out for a chainring specifically designed for single-ring setup (longer teeth). You could also keep the derailler on for a while to make sure the setup works for you. Once you're confident, you can then remove the front derailleur.
