Appreciate for any pointers.
If you mess up with epoxy, the paddle is ruined. I'd use a (relatively)
high temperature hot glue. You don't want something that will soften in
the summer sun. You might have to look around to find something a bit
better than craft store hot glue.
You can use heat to set the paddle blade position and if it isn't right,
you can use heat to change it. Once cool, the glue should hold fine -
there's likely a lot of surface area to hold.
Hot glue is used to hold baskets on carbon fiber ski poles all the time.

I'm not sure I agree. I use System 3 epoxy (pref 10min, but will use
5min) thickened with a little cabosil to glue paddles - in fact, that's
all I use. Hot glue works OK if the conditions are cool and will remain
so, but it will creep if warmed, typically to around 70C. A hot car
interior can easily pass that on a summer day - be very careful if you
go this route.
If you decide to change the pitch, or need to remove a blade to shorten
the shaft, it can be done - if done carefully. Heat the joint area
gently (I prefer boiling water), and then very carefully heat the joint
area with a hair dryer or heat gun and and carefully apply pulling
torque to the blade and shaft. It's best to have 2 or 3 people working
on this. When you get the expoxy warm, it will release (at least most
of the time). Starting off with the joint and surrounding material at
round 100C means less stress and shock to the material, and a better
chance of lightly and quickly heating the bonding epoxy to a breaking
point without doing in your shaft or blade.
Use thermal glue if you like - I'd prefer to save that for ski poles.
