Just use a wallet that lets you set the fee (I can't find a way to do it with Multi-bit, but Electrum lets you set your fee), and give it a try. It might take days for the transaction to go through, though, so don't try it with an important sum of BTC.
In general, though, I wish people would just pony up the 2.8 cents and feel good about supporting the network...
Yes,Multibit does not allow its users to be able to change the fees themselves. It is permanently set to 0.0001
