I like the proposed changes, with one exception:

Second Phase - Direct Elimination
The four teams will be paired to play semi-finals, according to their rank on first phase: p1 vs p3, p2 vs p4.
I think it would be better to use regular seeding matchups, so the team who does the best in the round-robin goes up against the team that did the worst (out of the four who advance). That is:
SEMIFINALS: T1 vs T4
and
T2 vs T3
This does more to reward great performances by a team in the first phase.
