Hypothetically, could I install two NIC cards on a desktop and bridge the connection to get 200Mbps instead of just 100Mbps?

So if I have two PC's with two 100Mbps NIC's with bridged connections, I could transfer data at 200Mbps?

What use would this have in the real world? If I wanted to spend the extra money, I could get two DSL accounts and bridge them for 3Mbps of download and .768Mbps of upload if I were to bridge the connections?
