RD Harness with Oveja Negra Lunchbox?

[Cadence]

Hi all ,

Has anyone tried fitting Revelate Harness with Oveja Negra Lunchbox?

I don´t like the the RD pocket in  size small ( or other newer solutions for front pouch ) and ON has the loops on top of the LB  for storing stuff. Plus I just like the design. I was eyeing the ON Front End Loader as it´s both cheaper and highly reviewed. Just a bit concerned of it´s capacity concerning handling weight.
As RDH can hold up to 15 lbs I´m kind of drawn to that --carrying extra water bladder on top off camping gear tends to add weight and ON hasn´t stated anything on the weight matter and for some reason the FEL looks a bit flimsier in this respect.

As for matching the Harness with the Lunchbox have tried to look at different pictures to see whether the straps of both would linger between each other -are the RDH ones narrower so that ONLB could be strapped around them? I do realise there´s tons of ways to secure them but wouldn´t like the strap and buckle to be of similar width that´s all.

Grateful for any insight on this
