Should work fine - I don't think the Big S has messed with the ring spacing on chainsets. Front mech will obvioulsy have to go up, and you may find a bit higher than ideal as the shape of the cage will be curved to fit 42/44 rather than 50/52 rings. Chain will need to be a bit longer, but you may get away with it if you are sensible with the gears.
Currently running 48/38/28 set-up on my AA with no issues with modern 9spd deore bits.
