Anyone care to comment if these light pre-preg composites are repairable if
damaged?

According to Greg Cole, it's not a problem. He went into a bit of detail
with me a few months ago, but I don't remember them well enough to pass
it on. Wet layup repairs can be made up to a point, as I recall. Of
course, the factory should be contacted first for the proper methods.
Every composite component is laid up in a mold and assemblies are done
in jigs, so you could buy replacement parts, even a wing, and have it fit.
