You can override the paypal api and change the value that are sent to paypal and you probably will need to override other methods that are validating the sums that are paid.

$ grep getBaseGran app/code/core/Mage/Paypal -rsn
app/code/core/Mage/Paypal/Model/Express/Checkout.php:180: $this->_quote->getBaseGrandTotal(),

app/code/core/Mage/Paypal/Model/Express/Checkout.php:246: $this->_api->setAmount($this->_quote->getBaseGrandTotal())

app/code/core/Mage/Paypal/Model/Express/Checkout.php:283: if (Mage::helper('paypal')->areCartLineItemsValid($items, $totals, $this->_quote->getBaseGrandTotal())) {

app/code/core/Mage/Paypal/Model/Standard.php:147: $grandTotal = $order->getBaseGrandTotal();
