Just to add, the key point to this part are the national CAA rules and regulations. And this should be the initial point at which to start any project like this. The lack of a national certification route of the final product makes any other costs moot no matter how cheap they might be.

FYI: It depends. For example, there is FAA guidance that allows the use of surplus and salvage parts in the repair and restoration of type certificated aircraft. Actually there are some models where this was the only option like Stearmans, Wacos, and other older tube and fabric aircraft. Even some conventional built aircraft have been brought back to legal flight status using salvage and owner-produced parts. At one time you could scrounge up enough parts and even without an original data plate build a "certified" aircraft. However, if you wanted a standard airworthiness certificate you needed a permission letter from the current TC holder to bless the aircraft. If no letter then you were stuck with a restricted AWC. Never heard of one of those letters ever issued though. While it can be economical to tackle a project like the OP suggested, most are not unless you are a A&P mechanic or get the mechanic work for free. Regardless, it can be an interesting endeavor.
