Is there a reference design/app note that details how to interface two of those eval hot swap board:

With a load sharing configuration? I’d like to have two blade PSUs (Intel G36234-013) with load sharing and hot swapping capabilities. Ideally with all components being from MPS?
Main specs would be a single 12V rail with 60A max (constant) current capacity OR-ed with another’s PSU rail. So that’d be a total of 120A@12V and hot-swappable… The MP5990/5991 seems already capable of handling that, but not the OR-ing part.
Other manufacturers app notes for reference on what I want to achieve:

Further examples from yet another manufacturer and details:
Hello,
I am not sure we have one for that part. However, the attached App Note has a section in the PDF version that details or-ing on page 14.

Gracias, thank you so much! 
Do you have a similar application note that combines both or were you suggesting to just use MPQ5850 and a suitable N-Channel MOSFET?
Actually, your OR-ing proposal with the MPQ5850 does (as far as I can understand) an ACTIVE-PASSIVE configuration… I would like to have an ACTIVE-ACTIVE configuration (load sharing). Are there any MPS application notes implementing this with the aformentioned power requirements?
Furthermore, would it be possible to separate/isolate critical loads from non-critical ones? As in: if one of the PSUs fail, I’d like to keep part of the loads active no matter what and shutdown those deemed non essential?
