Mallet dh, ht x2, dmr v twin or nukeproof horizons are probably as close as you’ll get.
As above with standard spd type shoes they won’t work well for grip,you need a set of clip flat type shoes ala five ten spd or specialized 2fo clip.
The grip on my mallet dh is i guess about 75% of my nano x when I’m not clipped in which is to say better than poor to average flats but not fantastic. Entirely rideable when I’ve picked up the wrong shoes… (Edit, not comfortable though as the mechanism stands a little proud)
50/50 pedals are bad, mechanism is always* on the opposite side to the one you want and they tend not to be good at either.
