A mixed thru-axle / QR update? Fork rake Q.

[polyhistoric]

So, I have a 2013 Seven Evergreen - disc brake, QRs. Enve QR fork, 47mm rake. Takes 38mm max. Updates to the read end to make it thru-axle are a no go. Can update fork...

Love most everything about the bike for meandering, mixed terrain, and less spirited road rides. Handles like a dream for its purpose.

I can change fork out to Thru-axle. Worth it?
I can change the fork rake from 47mm (71.5 Headtube Angle) to a 50mm if I want the newest Enve Gravel Fork instead of the Enve CX fork. Handling change for the better? By some accounts the 50mm would produce better handling, but I truly have no complaints about the 47mm.

The Enve gravel fork accommodates wider tires, and flat mount brakes if that matters.

What is the PL collective wisdom in the issue?
