What you're asking for in your OP is what's called nested ticketing. Generally speaking the airlines allow this and you won't have problems. Do it too many times and you might get a call - or worse your SM account get locked out. But generally you can do this two or three times and you won't have an issue.

There's a promo of 25K each way RDM for flights LHR-US. However, you have to have a UK address in your SkyMiles account to qualify and fly by 30 April.
