I am not sure to understand exactly your issue, and your explanation are not as easy as a piece of code to understand... But maybe not "removing" you field from the form with readable and writable = False, but instead just hiding it with javascript could be of some help... The thing is that if you field is set to readable and writable = False you will not have this field in the form.vars so you can make any verification with your onvalidation function base on this field....
Hope it helps.
