please read my comments. outside skills especially OD is way too important for SFs not to have due to the large amount of teams playing SGs at SF. also all these dream SFs will never likely to happend unless you train your player into 25-26 and that is without any training mistake, foul outs, injuries along with world class trainers and what not.
my suggestion can be easily done with a SF with decent starting skills without overextending by having 15,14,13. that is already a PF like inside skills which means you either have to have great starting inside skills leaving you with terrible outside skills and whatever the height is, it would be a pain training.
well if you want a "dream SF" then:
all legendary

now that is a dream.
