A quick comparison of the wings shows the Puppeteer's wings to be no more than 10% wider on the cord and about one rib bay shorter on each wing half. It would be easy enough to just add a rib to each side.

On the horizontal stab/elevator, the scale version is just a bit wider but at least 20% longer. If I go for the greater wingspan I'll also increase the size of the stab. Conveniently, the (positive) scale incidence on the Strutter is about the same as on the Puppeteer. I'd want to be reworking the stab seating area to be more scale as it is one of the distinctive features of the fuse and gives a bit of a curved up look. This shape allowed the incidence of the tail plane to be adjusted in flight -- which also explains the characteristic gap between the top of the stab and the bottom of the rudder fin. This arrangement was also seen on subsequent Sopwiths like the Tripe.

Does anyone happen to know how (when) the airbrakes were used? They could be cranked up to an almost 90 degree position. I assume this would be something the pilots would do after landing.
