Nope. Doing the traveller's temporary suspension on the wireless line suspends everything, so you can't forward any calls since the line is not capable of recieving any calls while suspended, same with SMS.
I'm not aware of any other way of doing that except to keep your line active on a cheaper rate plan. Then of course you run the risk of your current plan not being offered when you get back.
Or you could switch to a Share Everything+ plan and get Roam Like Home and just use the one phone, and ditch the US sim.
