There's considerable historical evidence (and thus, debate) that the 1737 ship is a completely different vessel than the one at Trafalgar.
"Lifespan" of "green-built" Royal Navy shipswas only about 20-30 years. The timbers simply would not hold up, or shipworm would get to them eventually, at least until using copper plates gave some protection.
RN ships "in ordinary" were often "refit" per the parlence of the day. Which meant they were taken down to the keel and rebuilt from the frames up. The body lines were not necessarily well-matched, from the old to the new.
Wood is wonderful product, but, to be durable, took extraodinary effort.
There is a school of thought that suggest that building a 1737 Victory from an 1805 is a bit like modeling a Hurricane from a Spitfire. It's possible, but may be far more work than a peron might want to do.
Nelson's Victory is 10-12 foot longer, which is insigificant at 1/100, the additional poop deck and stern castle will be more telling. Also, from memory, the stern castle is narrower than the 1805 ship, and with open galleries, not closed.
But I could be misremembering, too.
