I don't see a reason not to do this.

How much extra pitot line do I need to keep at the wing root?
Is there typically a connector in the root area to connect it to a run in the fuse?
I wouldn't think that it would need to be one solid run all the way to its destination.
Looking ahead in the plans, I didn't really find any mention of this, although maybe I missed it.

I prefer to have no connection at the root (one less likelihood of a leak), and I usually leave a loop at the root that if I need to remove a wing later , it will give me slack to install a connector later.

Questions before buttoning up the QB Wings
In my RV-9A I have electrical wires running where your green pitot line is and I wanted to secure them in the bay where the aileron belcrank is. I made a couple (for top and bottom) of sheet metal hat shapes (about 3/8" wide) with a hole in each end. I mounted these to the bolts that go through the spar that fasten the tie down extrusion. Then used a tie wrap to secure the electrical wires to the hat section.

AOA and Pitot tube
Howdy,
I elected to use a bulkhead fitting for the aoa and pitot tube that was sold by Stein. If not when the lines get into the cabin there is only about 2" to make the bend and go forward. I do realize there is another place for air to leak though.
I also started with the Dynon heater controller mounted where you have it on the wing rib, but elected to change that to the access panel for ease of being able to service the unit. But, like someone else mentioned, at a minimum change the phillips head screws to allen or a bolt. Just make sure you can get to the unit for service

Fittings
I opted for the bulkhead fittings at the root for the pitot and AOA.
With the push on fittings that most are using, leaks are possible but not very probable. Is it another place that might leak, yes but where do you draw the line? Large trucks use many of those same fittings for their air brake lines and they are pretty reliable in that application with significantly more pressure...
In the end, it amounts to what you are comfortable with...

AOA Controller mounted to service plate
For the AOA controller, I mounted it directly to the service plate.
It makes future service easy.
Photo was taken before the alloy lines were bent .

Which "plate" is that mounted on?
Is it inboard or outboard of the aileron access?

Careful with this. That pitot mount should have support from a rib as well as the skin.
