I would go the heat method, it's what we do where I work. As long as the epoxy has not seen a great deal of heat previously it will soften quite easily. Usually the laminating resins that were use to lay up the fuse has a higher temp rating then the epoxy glue used in production. I have been successful removing brackets from a honeycomb panel that were glued in place with a Hysol product 15 years prior to removal by just using heat and some patience. Popcicle sticks that have been sharpened are great for this type of work.
