I'm still not sure what exactly your plan is. Just moving your landing/marketing page or the whole ecommerce frontend? WordPress is nice if you need a blog or at least a CMS for luser or if you need some framework to build on. Is that the case? Maybe it's a useful abstraction (e.g. uptime, maintenance, development) and maybe it's good that someone without developer knowledge could work on it, but you told it would need a lot of integration work? Sounds like you should create an API then. If you need an API anyway, than this actually would be a great way to test it in a real environment. Otherwise likely unneeded effort. To speak about WordPress plugins, please mind, that most of them are rather simple. Hook some button code and JavaScript somewhere and offer some simple configuration backend UI. Deep integration for any features the user might see often needs custom CSS work, editing the site template or even coding within the plugin. At least that's my experience with my personal requirements. Or to say it in different words: Integrating Facebook buttons isn't that hard anyway, but a professional newsletter would be a lot of work anyway. Also you could likely reuse the plugin code and transform it into Rails code.
