Usher Wants to SETTLE With Ex In Wake of Jet Ski Tragedy

Usher has changed his tune and now wants to up his ante to settle his epic child support/custody war with Tameka Raymond after the jet ski accident that left his stepson Kyle brain dead ... Dannydigit learned.

Sources connected with the couple states... Usher spoke with Tameka over the weekend and suggested that they settle up, but he did not significantly change his offer -- 50/50 custody with a very slight increase in child support.  Tameka said no way.

But apparently Usher softened after the conversation, because our sources say he met with his lawyers earlier this week and instructed them to craft a new proposal that would give Tameka "a majority" of custody, though the sources did not specify the exact breakdown.  We're told Usher is also raising his child support offer "significantly."

As for Usher's motivation ... we're told he's very conscious that Tameka is suffering and it's not a good move to continue the fight under the circumstances.

We're told the offer has not been presented to Tameka yet, but our sources say she's open to a "reasonable settlement."

Calls to lawyers on both sides have not been returned.
