Upon seeing the back of that stub wall, I can't understand why someone felt the need to mount that load center horizontally. It's almost square.
I'm also none too happy with the supporting of that panel. It looks like the only thing holding it is a couple of cut metal studs and the drywall.
I'd rotate the load center so that all of the breakers are compliant, then chip out enough of the slab to get to the coupling in the floor and drop in a concrete-tight coupling to turn the conduit to the wall. Turning up out of the floor into that wall will still be tricky. Be aware that there may not be a coupling in that conduit run that you can start your run at. You might be seeing the bitter end of a 10' length that starts at the box and goes 'wherever'.
BTW, is that a low voltage cable that just dives into the concrete???
