Recoring question

[CHANCE1234]

There's a thread going about an entire top cap needing to be record which got me thinking about my cap up by the bow where I want to reinforce it for a swivel rod holder. The boat is a 1972 20 CC. My cap is solid glass except for the bow area where there is balsa or plywood. I want to avoid removing the entire cap so in the picture below here's my plan: cut the top cap about two feet forward of the gunwhale rod holders on each side,then cut the two vertical pieces right near the bow about half way down then remove that section of the cap to be able to turn that piece over and remove the old core and add new/better coring that will better support the rod holder. I'm pretty comfortable glassing as I've done the deck and transom and the engine has yet to fall off. The picture is old, when I redid the deck but it's all I got now that the boat is shrink wrapped. Does this seem like a good plan?
