As referenced in Higham's blog post (https://nhigham.com/2015/08/05/anderson-acceleration/), Anderson acceleration can be applied to the alternating projections method to achieve a speedup of 2-3x. The paper can be found here: https://link.springer.com/content/pdf/10.1007/s11075-015-0078-3.pdf
Higham has matlab code for this method found here: https://github.com/higham/anderson-accel-ncm
