I see your point but I think Madrid's institutional attitude and identity is more about winning than anything.
Our identity, or philosophy, is closely associated with style. I'm not saying it must be 80% possession all the time, but I believe it would be a mistake to deviate from attractive football for the sake potential short term success.
Football fans are both greedy and have a short memory span.
The whole Barca style is more or less a marketing stunt, it is something that sells and attracts fans.
It attracts more fans when they feel they are loyal to a brand type of football, it separates you from other clubs.
But when this type is not winning titles you lose that edge you have.
When we are winning and playing good, it is easy to brag our style of football.
When we are winning but not playing well, fans will be dissatisfied because they want more. We want attractive football, we want Barca football again, where is Barca DNA.
But once we are not winning, fans will want the titles again. Fans of any team will choose Chelsea's Mourinho over Wenger Arsenal in his late years.
When EV was hired, we were 1 year away from a dominant Barca side that dominated football for 2 years, fans were saying why we should give EV credit for winning Liga when we were winning it anyway. They demanded our football back.
But now we are 4 years away from that attractive football, next year we might be 2 years away from titles.
If they get EV ball (metaphorically speaking) again with winning they will gladly take it, for a year or two before demanding attractive football again.
The football they played with Mourinho was good apart from vs. Barca and Bayern until his last season.
Lightning quick counter attack football. Scored loads of goals.
Irrelevant, they hired Mourinho because they thought he can beat Barca after one of the most epic bus parking ties we have ever seen.
He even bragged about he doesn't want the ball.
