I highly recommend not going with the EC90. The handling change will be drastic and for the worse. Yes its personnal preference, but I'm with Tri-Guy in that a bike with a 53mm trail is not nice to ride being horribly twitchy and it takes constant concentration of the road to ride no-handed (such as stretching and eating) because any little wheel wiggle and the bike wants to dive into that direction.
It's going to take some real searching to find something worthwhile and considered an upgrade, while still maintaining the handling. 1" fork options are now very limited, and in any size forks with low rakes are also limited.
Reynolds got out of forks
ITM - no 1"
Easton - Don't have the rakes
Enve/Edge - doesn't have the 1"
Pro-Lite - no 1"
Columbus Minimal - rake to big
Kinesis - makes lots of forks and lots of rakes. But most are cheap OEM-spec stuff and almost 600 grams. Is that really an upgrade?
Control Tech - wrong size and rake
3T - wrong size and rake
Some company may have made a 40mm or under rake fork in 1" long ago so it will take searching to find it.
Whoa - here it is!!! 1" steerer, 40mm rake, 400 grams, and Ouzo Pro was great fork!

If 9" of steerer is enough, and maybe just with a 60cm frame, then this is seriously a perfect upgrade fork.
