I know of two JDM baitcasters designed for "Area" trout fishing (there may be others). One is a Daiwa, new this year, which I have ordered but have not yet received, and the other is a Rodio-craft, which I decided not to order because the blank is bright yellow (I may order it anyway, though). The Daiwa is a 6' two piece rod designed for 2 - 5 lb line and 1.5 - 5 gram lures roughly (1/20 - 3/16 oz). Rodio-craft does not list recommended line and lure weights but I suspect they would be about the same as the Daiwa rod. I have not heard anyone in the US even mention Rodio-craft rods, but they have a range of spinning rods designed for Area trout fishing that range up to roughly $750 - so they're not junk. The Rodio-craft baitcaster is one of their less expensive rods (no cork and no wood) and is 5'2", so I would probably use for UL stream fishing instead.
Your jig and float would be right at the lower end of the recommended range (and also right at the lower end of what people can reasonably cast with a BFS reel). I have not used a float/fly rig, so I don't know if that adds any difficulty.
If you are already an expert with a baitcaster, you shouldn't have a problem. If you've always used only a spinning rod, be prepared for some frustration, although you may eventually learn to love it.
