laminating wood for large hi tech wind mill blades) that is extremely
viscous. I have also heard of carpenters using an ordinary vacuum cleaner
and a plastic bag for laminating jobs. It would important to draw off any
air pockets

All the adhesive approaches would have some problems due to the various
incompatibilities already discussed.
Have you considered making a visible repair by pinning the two
