When I re-cored the cockpit of Calypso, I put in the new coring (plastic 
foam) in three sections, wrapping the glass down to the bottom laminate 
in between.  Tying the laminates together like this will keep the 
cockpit rigid even if the bond to the coring fails.

Most likely, that's not needed.  Yours sags because the upper & lower 
skins are no longer are connected by a solid core.

If you end up with a sag after doing the job (as I did), then you can 
fair it level with resin (I used polyester) mixed with glass beads. 
That makes a hard surface that can take the wear.
