no, unlikely. Taiwan could have developed an indigenous capability with south african assistance only....hell, south africa HAD nuclear weapons. had enriched uranium. had local suppies of uranium ore.
Taiwan has never had the industrial background to obtain such a project. While it is true that Taiwan wouldn't lack the scientists, the light-industry centered economic development would mean that Taiwan would either need to do uncharacteristic industrialization or seek external help.
There seems to be misunderstanding about given how South Africa (and recently, DPRK) have obtained nuclear capability, it is easy for any small but determined nation to do that. It isn't. Weapon-grade enriched uranium isn't going to be moved around without getting noticed (especially from South Africa to Taiwan), and both countries have one of the world's greatest reserves of uranium (believe it or not, DPRK has 4
million tons of uranium ore) to exploit. Also, isolation forced both to retake a lot of heavy industry buildup, forming the backbone of any nuclear weapon programs.
In short, no amount of help from South Africa would give Taiwan the capabilities to refine the necessary amount of uranium or plutonium to make nuclear bombs.
and Taiwan doesn't need alot, just enough for minimum deterrence.....
Yes, but still, how are you going to get that much uranium/plutonium to produce the dozen or so bombs?
Taking all of this together, there is only one ally which Taiwan can look to, and that is ROK. Now, given Parks disdain for Chiang, things might be rough, but I find it possible for a working relation to be formed with bombs being made by 1975.
