Payment page configuration problems

Hello!

I am trying to create a community website using Drupal.

It has a paid membership for users.

I used this technique to achieve the results:
1) created a roles that assigned after successfull purchase
2) installed ecommerce module with recurring products
3) configured recurring products that if purchased account must be created (if no account exists)
4) activated a authorize.net and paypal eccomerce modules

Now I have a problem.

Is it possible to add option at payment method select form to pay by check or bank wire? If that option selected than a simple registration form must appear and registration must come as usual (but without role assigning after end of registration)?

Thanks!
