For the two Henley-related items, I think that the "Hawker Henley Close Support Bomber" was just the original Henley design as embodied by the prototype K5115 with a single gun in the wing, one on a pintle for the gunner/observer, internal bay for 550 lbs of bombs and another 200 lbs (8 x 25 lbs) on the wings.
A developed Henley, say with twin flexible guns, a few more forward-firing guns or a couple of 20mm cannon, a later and more powerful version of the Merlin, added armor, etc. might well have been useful and certainly more effective than the terrible Fairey Battle. That said, the Allied concept of a fighter-bomber seems to have been an even better alternative--there's not a lot that a flight of Henleys could do that couldn't been done as well or better by a flight of Hurribombers, which can also mix it up as fighters once they drop their bombs.
I have never seen anything on the "Hawker Henley Escort fighter conversion" other than a couple of remarks to the effect that it might have made a good one (such as the LIFE magazine caption below). Mason's HAWKER AIRCRAFT SINCE 1920 says, "Hurricane and Henley...outer wing sections and tailplane were built on identical jigs, though of course the eight-gun battery was absent from the Henley." Presumably, then, an escort fighter conversion of the Henley would be as simple as replacing the Henley outer wings with the eight-gun Hurricane ones, deleting the rear gunner's position and fitting the bomb bay with a large fuel tank.
Again, though, the result doesn't really seem worth the trouble vs. just using a Hurricane. Late-model Hurricanes could carry of pair of 44- or even 90-gallon drop tanks and it wouldn't have been hard to come up with slightly modified long-range Hurricane with an extra fuselage bay or larger wing center section to carry that fuel internally and avoid the drag penalty of the drop tanks.
