This first box is partly a retort and will circulate tarry gases which I would expect to obscure any windows. > > > I think the throat between the two will suffer. > > I've got some thick plate I could use for this part (I could fabricate > the stove so it can be easily replaced.

Possibly too massive, something like aluminium silicate sheet or thermoboard. Sheet steel will survive 700C if it ambient the other but here you will have up to 1600C on one side and the rejected flue gas ( 200ish if the heat exchanger is good) the other. Thicker plates normally do worse than thin because the hot side gets too hot as the interior cannot conduct heat away fast enough. As you have a wet system how about more complication, a water jacket insulated only on the secondary combustion side.
