The best solution is to replace like with like in this instance.
Wood's durability is of course well known, and it will behave the
same way as the original material. If you do not have the
skill/capability/proficiency to carve the replacement I suggest that
you work on developing this skill. The result, in the end, will be
better, plus the time invested in developing the skill will pay
dividends in future projects. I can advise on wood bleaching and
colouring techniques that will mimic the faded mahogany appearance.

There are quite a number of good carving books around; check out
Taunton Press books (Fine Woodworking). The best thing is just to
try it, and from my personal experience the foremost tool in carving
is a sharp pencil. Next is to know how to sharpen the different
shape chisels. Drawing skills first, however!
