Can you put Alpine finish over existing alpine?

Hi.
I have just had a garage conversion done and my house is an alpine finish, the plasterer recommended patching in the areas best he could but has said he may be able to over lay the hole area (please see picture) if he puts on a coat of sbr!!!
My question is will alpine stick over alpine of is he best going with original plan and just patch the area in?
Thank for any advice.
