The ply really needs replacing!

However, thinned epoxy, run into the seams may help to bond it back together, I think they do make epoxy thinner, but I've never used it, I prefer to use meths, which evaporates quite quickly after allowing the epoxy to run into the seams and leaves the epoxy behind. Use a slow hardener.
There is another stuff, Gitrot, but not really whats needed here. All of the above is a temporary repair.

The standard slow curing epoxy for boat building doesn't need thinning. It'll find it's way through anything. You can make dams out of Plumbers Mate to contain it.
If the laminates are genuinely rotten then although the epoxy repair will suffice for a while a sharp blow will shatter it. New wood sounds the best route. Not as difficult as it may seem.
