Door panel wear/crack - upholstery, wrap Options

[Mirstanov]

Hello, guys. Im new to the forum.
Excuse me if this post duplicates but I searched and searched and could not find anyone with a remotely similar problem as me and a solution from experience.

My 95' Celica door panels are in a horrible condition - they have these weird bumps on them as if the foam (if it has?) under the vinyl/leather has degraded and on top of that the hardboard behind has cracked in a few places.
Is it worth tearing the old vinyl and foam and applying new ones OR wrapping the existing panel in a leather textured vinyl imitation, ignoring the bumps ? Also how could the cracks in the hardboard be fixed ? I assume by gluing a small piece of wood on top to keep it strong and intact ?

Im guessing the wrap, although not impossible, would be quite challenging due to the complex design of the door - many curves etc.
