How can I limit the *sum* of upstream plus downstream traffic on my WAN

Unless you have a half duplex wan and I don't understand why you would
need to limit the sum of up and down.
Thanks Andy, our subscription is for 1.5mbit, and our traffic graphs
show that the sum of our upstream and downstream is never more than
1.5mbit. When the connection is saturated and one goes up, the other
goes down.
OK, so what is the nature/bandwidth of the link - this can affect what
you need to do WRT rates.
If your ISP is artificially limiting you to half duplex and the link is
full duplex/higher bandwidth you may be able to push the rates a bit
higher than if the limits were the link and depending on what the ISP
does buffering/latency may be less of an issue.
It's possible due to acks getting buffered to see uploads affecting
download speed even on full duplex links. You can avoid this using tc.
What do you want to achieve with your shaping?
