Yes, it is possible but the hexagon on the starter dog lies behind the little alloy housing on the front of the timing case. Unless you have a very deep socket (I forget the size off-hand), access to the hexagon is poor without stripping the front of the timing case and there should be a lock washer present. Stripping the case is quite a complex job as that front panel retains the timing gear bearings.
However, it may be worth checking the alignment of the handle shaft and the dog, through the cast iron guide. A few degrees of error isn't a problem but my Chummy took a lot of lining up and fiddling with the guide (reproduction part) to get reasonable engagement. Even now, the handle is good enough to turn the engine but I wouldn't like to try and start it that way as the engagement is still not 100%.
