For me it's the same if you want to go for individual the trophies. The really difficulty is going for the treble.
If you want to go for the Cup, then you must end with a low quality team so to have a draw with teams near your level and quality and then in the beginning of the season to enforce your team but the the league and the CH.L. will be very hard.
The most I had, going for the Cup with a good quality team was 2 semi-finals and 2 times final 8.
I 've played all my finals with a team of 6* and 2-3 (early) 7* players while my opponents had 5* and most 6* players.
* of course it needs concentration and good luck
