Here's another thought that's worth what you paid for it:

Instead, create a single TCP connection for each link that you want to
use.  Create a muxing layer on top of these connections that distributes
data across the connections in a possibly uneven manner, filling the
buffers of each connection.  This layer would require some additional
framing and sequence numbering.  On the receiver side, demux using the
framing and then reorder the arrived data.  Now, you're using the full
bandwidth of all of the available links, and saturating them up to their
full TCP performance level.
