I think that it's more interesting playing 12 different teams, than playing twice 6 different teams.
In short, in general I'd agree with this. However, everything also depends on
-a league system used and
-number of teams participating
-how many divisions there are
-how many groups there are in the LEAGUE (there could be multiple groups within the same "league tier", like in Eurobasket/World Championships for instance)
-how many groups there are in the DIVISION (there could be even 2 groups in a division/league where as little as only 8 teams play)
-how teams play the league (there are so many potentially very good and interesting league systems out there, of which many are used in different sports, and of which many would be well suited to basketball too).
-etc.
Choosing a league system is always a some kind of compromise. In a way it'd be interesting to use more unorthodox systems, but on the other hand for the majority of managers it could also seem as off putting (as they might be only familiar with the most typical league systems), which I don't know/say as a fact but just speculate about it here.

*In case of a sum of MORE THAN 15 teams :
- the 1st season : we create 2 divisions based on salary mass (SM). Biggest SM goes to 1st division, 2nd SM goes to 2nd div, this up to the 16th team (or more). After playoffs, we create :
- a UPPER division with the 8 best from last season
- a LOWER division with the 8 worst
In this example of yours (based on salary - but I wonder what you mean by salary mass? Team total salary? I'd prefer other method of calculation, as suggested in earlier text), how did you think of deciding 2nd season team divisions, as 8 playing in UPPER league ARE ALREADY better than any of LOWER division teams after season 1 (as different level divisions aren't really comparable and therefore comparing different divisions playoffs results in order to determine which one is a better team couldn't be made; for example, you couldn't say that LOWER division playoff winner would be 2nd best of all teams, etc.). So it appears to me that the UPPER and LOWER division are initially based on SM, and as team comparison after season 1 playoffs can't be made objectively, then "normal 2 teams up 2 teams down" relegation schedule would take place starting from season 2 (and in that sense, no such "league creation" would take place after 1st season)?
Few thoughts:
- some league systems work better when there's more random number of teams playing (such as an odd number of teams, or in the case there would be hardly enough participants left for 2 divisions such as total of 13-16 teams), so keeping an open mind to a possibility to change the league system from season to season could be beneficial. I'm generally open to discussion on many kind of league structures, even though I do have (strong?) preferences too in some cases.
- if we want to play more games (including playoffs) than there are in the BB season, we could have 2-3 game days in the week. But it'll be necessary to evaluate if that'd cause too much organisational work
- it'll be necessary for every participating team to take care they'll have enough tokens left to organize matches for the whole season
- it would be possible to keep it as same division league with as big number as 16-18 teams if we want to (like in BB league there are 16 teams), even though then the relegation scenario wouldn't be used.
- relegation/promotion scenario, should there be multiple divisions, could be implemented in many ways. One of the interesting methods could be the one used in English football league system (amounts divided by two here): winner gets promoted, and 2nd and 3rd will play a promotion match (team with better regular season record maybe getting a home game?).
