How can I hook bp_show_blog_signup_form() or bp_create_blog_link or other related function?

I want it not to show registration blog content. I mean when user “has limited his numbers of blogs per member” there is no link to create a blog.

Or even better: There is a link, but without blog signup form, but with the message: ‘Limit nine blogs per member. If you would like another, please contact an Admin for assistance.’

I do not want to hard coding in member-themes’ files. I’m creating a plugin with Admin page to configure this.
