I'm on board the Ricky Rubio train for sure, but another option which would pay much more immediate dividends (and may work better next to Brandon)
Steve Nash now, Stephen Curry later...
I think Curry's stock dropped this year, and I think he'll be available in the 12-15 range, he's an incredible shooter, and I think his passing is very underrated. Nash we've debated quite a bit, but I personally believe he could work great next to Roy, as Roy can be much more dangerous as he learns to be a threat off the ball too (we're seeing this a little now in his current tear as he's cutting backdoor a lot and spotting up really well), and Nash is a great shooter who can still spread the floor even better than Blake.
Curry could fit in well as a non-fantastic defender yet tough and smart complement to Brandon as a fantatstic shooter and master of getting open in the half-court, like Rudy. He could be tremendous with good bigs and might make Oden and Lamarcus' job much easier. Another thing about Curry is how good he is at passing the ball (perhaps not in a PG role)...Bob Knight elaborated on this a lot in this video and really sold me on him.
I know other players' athleticism will give him trouble in the league, however his game isn't based on athleticism now and he's extremely intelligent, saavy, and a hard worker who can be a pesky defender and active in zones.

down the line a primary backcourt of Roy/Rudy/Curry is unconventional but sure can stretch the floor and play off the ball well.
I think a trade of Blake/Bayless/our pick for Nash/Curry could be a very good basketball deal for us, and a great financial deal for them (saves about 7 million) while giving them a reliable vet, decent pick, and good young prospect who's local.
Nash/Sergio/Curry/Koponen
Roy/Fernandez
Webster/Batum
Aldridge/Outlaw/Freeland
Oden/Pryzbilla
solid mix of youth, vets, complimentary skills, and a lot of shooting.
