L52 will be 0 ohm resisteor and C63, C64 is not equiped at first.
I add vias... as you suggest.

RF path width is 0.762mm which is same from reference design of yours.
Is it OK?

Looks mostly good.
Schemtic is ok.

Adding the extra pi is nice to have, you can leave the two caps N.C and have a 0 ohm series resitor.

I would add some extra vias around the areas where a marked here, always better to have good GND connection.

Also along the RF path I would add vias that tie the ground planes together.

The C62 component can be removed if you want. So you dont need to have the footprint in the layout.

Looks ok.

Jonathan

I've revised the layout by adding an external Pi-matching circuit outside the shield CAN. I'm currently using a $0\Omega$ jumper for the series component (L) to test the initial RF performance.
