Ian, my email is buggering about again, so I've not been able to email direct. For the benefit of others as you've posted here, I'll give my opinion here too.
The Falconar F11-3 is basically a Jodel D11 variant with the wing crank one bay further in and a three piece spar (For those who don't know). Any prop/engine combination approved for the D11 will have a pretty smooth run getting approval from the PFA. Talking of smooth, Pete Smoothy of Airworld's advise re prop/engine combo is worth taking, as he deals with most of them. If the engine weight remains the same despite upgrade to 0200 (which it should), prop weight must be checked. A couple of lbs difference right at the front may not seem much but the lever arm is high so it's possible it could effect W&B although unlikely. If the prop is finer, then I'd be surprised if the diameter was the same or smaller? It would be a bit like putting a lower range gearbox on a more powerful engined car ... unless of course the original was way out of spec??? (wouldn't surprise me in our case!). Also, prop spec's, although the same, often have differing performance depending on manufacturer. As an example I had two props for my old VP2, a CL 57X32 and a RWG 60X29 The CL was theroretically a better cruise prop, but in reality made no difference to cruise, but didn't climb half as well as the RWG. Nice prop though with lovely inlaid brass leading edges ... 1.5 lbs heavier for it's loveliness.
