So I've released a preliminary build of the new DoF + AO, which also contains various changes I made.
If you DON'T
want SSAO, nothing changes for you, as AO is disabled by default. You won't even feel it. Also you can use SSAO without DoF, DoF functionality can be toggled off entirely.
What's new: SSAO (obviously) and a new post blur mode, which basically runs the bokeh blur a second time. It's a lot sharper than the gaussian one, basically looks as if you used 3x the quality parameter so if you're into sharp bokeh effect, switch to post blur mode 1 and lower quality for a good fps boost.
To get started with SSAO: as ENBSeries compiles every technique the file contains, I disabled those techniques by default to keep compilation time low for non-SSAO users. To enable these techniques, open the file and set ENABLE_AO_TECHNIQUES to 1, save file.
Click on APPLY CHANGES in ENB UI and voila ,there are now ADOF, ADOF + AO, AO techniques. Also, there's a set of new parameters, prefixed with "AO:". Most of the stuff there is self-explanatory, IF NOT

and read up in the PDF file that comes along with it. Some parameters differ a bit, but most of it is coherent across implementations.
Sorry, this SSAO doesn't have SSIL available - without the ability to sample miplevels, performance of SSIL is unbearably low. SSAO performance suffers from that a tiny bit as well but not so much, the algorithm can run with as low as 4-6 samples (compare that to HBAO+ 32 samples^^) with a somewhat okay-ish looking result. Default params are just fine.
This is AO with 5 samples (lower than ENBSeries quality 2 afaik), no filter (raw, noisy result), still maintaining a stable result (motion flicker is non-existant):
With filter, other scene:
