One option that might work is methacrylate resin. It was discovered by mistake in WWII to be a safe option for implants. As physicians, we now use it to "glue" in artificial joints and to join broken bone. As you might guess, it is biologically safe for humans. I assume it might be safe for reef inhabitants, but I'd do research. The draw backs might be cost or the volume required. A ideal solution might be if someone had medically "expired" kits.
Have a great 2022,
