Just a second thought Stefan, and I checked the pictures on

As it was stripped internally already to serve as a Gun Tower, I think the logical bits to remove for conversion to Recce are already gone. You would have to put the top deck and driver's hatches back on. These can be fabricated, Adrian Barrell has done this many years ago.
Just add a radio in an appropriate location - vital for it's role as a Recce vehicle, not so much as a gun tower - add a MG and you're done.
Attached a picture of a Stuart VI Gun Tower, just for reference - and because I couldn't find a new Stuart VI Recce picture ;-)
