I would not add foam, the issue is getting the covers to fit correctly and not show any edges of the added foam. You can try to add some under the original foam, but it still is not easy to get the cover to fit properly.

Shaping the foam is not that easy. You can trim it with a razor knife, and sand it with an angle grinder with a coarse sanding disk, but unless you've done it before, it can take multiple attempts, it takes practice for good results. Kitchen electric carving knives don't work, I've tried. Hot knives make a mess, and create 'crusty' areas.

The replacement foam 'kits' are only shaped 'in general', better than starting from scratch, but they are more geared towards chevys, and still take considerable work.

Unless something is over-compressed, deteriorated, missing, or falling apart, don't change it. That's my personal opinion and suggestion for 1st timers.
