Actually, you consider gold only, which is not relevant as the most expensive part of the walls upgrade is possible with gold and elixir. Now all 300 walls are possibly upgraded to level 12.

Cumulated price of walls 1 to 8 (gold only) is: 821 050 x 300 = 246 315 000 coins Time to farm that @ 24500/hour (7 gold farms producing 3500 each) is 1.15 years

Cumulated price of walls 9 to 12 (gold and elixir) 10 000 000 x 300 = 3 000 000 000 coins Time to farm that @49000/hour (7 gold + 7 elixir farms farms producing 3500 each) is 6.99 years

So in total 8.13 years.
