Hey Simon,

Absolutely you can use your own login / registration form. Firstly you can do this by making a Child Theme and then completely removing the login and register functions from the spHead.php template leaving just any login / register buttons you have on your site, and secondly you can give the login and register functions a URL to visit once clicked by adding an argument, using your membership plugins login and register form URL's.
