If you have the right pasture plants, right rotational pasture set-up, the right breed of pig, the right bloodline of that breed, and the extra time, one could finish a pig. But it wouldn't necessarily be fat. It would be finished ready for slaughter. It takes a lot longer for a pig to go from birth the slaughter when fed this way.
I've raised some of my own pigs on pasture, but also fed them cooked garden products, foraged foods, and kitchen waste. The perennials in their diet included coconuts, mangos, bananas, pineapples, guavas, breadfruit, papayas, sweet potatoes, cholesterol spinach, chaya, pipinola. There may be more but they don't come to mind at the moment.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
