I need some help. I have a FSA SL-K Light crankset with 170mm cranks and would like to downsize to 155-160mm. Do I need to get a new crankset, if so, can I use a newer ultegra 12 speed on my 11 speed cassette? It seems like the 11 speed 105/ultegra cassettes only came in 165mm and higher. Is there a way to just get new cranks? See photos of current bike components. Thanks!

New crankset – yes
12s crankset on 11 speed cassette – yes
If you get a shimsno crankset, which are 24mm axles, you also need a new BB. As I can understand your current crankset is 30mm axle, or use adapter sleeves to downsize
