I really like the idea of Arcade Mode almost being like another career mode with its own rewards, but I think they could be toned down a little from GT3. Specifically, I don't think the reward(s) should be a race car like the Panoz Esperante GTR-1 was in GT3, but instead more like something you'd get from getting all golds on one of the more basic licenses. That said, I think Circuit Experience is a good replacement for both the Time Trials in GT3 and the full-lap license tests seen in GT4. So I think Circuit Experience should stay in some form - including the idea of only obtaining a reward for getting all golds, considering how many circuits and layouts there are - and the form that Arcade Mode takes in GTS could be combined with that of GT3, where there are rewards for clearing all courses on a given difficulty. But perhaps instead of there being three or four rewards (one per difficulty), the courses could be divided up, much like in GT3. Perhaps, instead of something somewhat arbitrary like "Group A/B/C/D/E/F" it could be by the type of circuit, namely original, dirt/snow, city, and real circuits, with a reward being obtained for winning a race on every layout within each group. The reward, of course, would relate to the motif. So perhaps for the dirt/snow group, your rewards could be a Ford Focus ST for easy, the road-going Lancia Stratos for normal difficulty, and the Pikes Peak-spec Audi Quattro for hard. In addition, if Circuit Experience returns, I think they should feature other cars, besides just Gr.1/Gr.B/Gr.3/Gr.4 cars, and have it be much more dependent on the course. For example, instead of featuring the Aston Martin Vantage Gr.4 for the Goodwood Circuit like it does in GTS, I'd personally pick the Aston Martin DB3S. That said, I'd keep the Porsche 919 for Le Mans. I'd also keep the Honda NSX Gr.3 for Suzuka, but I'd also feature a Gr.2 car for Fuji Speedway. EDIT: Upon taking another look, maybe the rewards for single race could indeed be like those in GT3, in that it unlocks cars only for use in arcade mode.
