Allow alternate credit card and PayPal text/logos at checkout

The Ubercart PayPal module for the Website Payments Standard method lists some logos during the checkout. In a glance, it shows the customers which pay services are accepted.
The logic behind this, resides on ...\sites\all\modules\ubercart\payment\uc_paypal\uc_paypal.module:

  $cc_types = array('visa', 'mastercard', 'discover', 'amex', 'echeck');
  foreach ($cc_types as $type) {
    $title2 .= ' <img src="'. $path .'/images/'. $type .'.gif" style="position: relative; top: 5px;" />';
  }

I think that it should be possible to change that text/images to adjust they to the local country PayPal's services (or custom needs).
For example: http://www.paypal.com/en_US/i/bnr/horizontal_solution_PPeCheck.gif (for US).
In my specific case, I needed:

<!-- PayPal Logo --><table border="0" cellpadding="10" cellspacing="0" align="center"><tr><td align="center"></td></tr><tr><td align="center"><a href="#" onclick="javascript:window.open('https://www.paypal.com/it/cgi-bin/webscr?cmd=xpt/Marketing/popup/OLCWhatIsPayPal-outside','olcwhatispaypal','toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=yes, width=400, height=350');"><img  src="https://www.paypalobjects.com/WEBSCR-640-20101108-1/it_IT/IT/i/bnr/bnr_horizontal_solution_PP_178wx80h.gif" border="0" alt="Che cos'&egrave; PayPal"></a></td></tr></table><!-- PayPal Logo -->

I tried to get this by using Ubercart Checkout Tweaks module, but maybe it is better to have it managed in the Ubercart project (as stated in http://drupal.org/node/1001248#comment-3841750).
Thanks In Advance.
