I've tried priming directly in the bottles before with the dual goals of priming more consistently (I was having issues with priming syrup not distributing throughout the bottling bucket, which have been reduced by ensuring I boil the priming sugar in water, rather than just mixing it with boiling water from an electric kettle) and saving time by bottling directly from primary. I did one batch with sugar measured on a scale that measures to tenths of a gram and another where I boiled a sugar solution, calculated the OG, and used a sterilized syringe to add it to the bottles. Both methods ended up taking just as long as using a bottling bucket and were more labor-intensive, and the batch that was primed with dry sugar in the bottles developed an infection to boot.
I know that's not exactly what you're suggesting, but I decided after those two experiments that bottling from the primary wasn't worth it and went back to a bottling bucket. I guess my point in writing this response is to say that I tried two fairly harebrained methods of bottling from primary and completely skipped what you're suggesting because it seemed too silly even by my standards - since you're waiting for the trub to settle out again (presumably minutes, as hours or days would likely have the sugar fermenting out before you bottle), you're not really saving any time versus a bottling bucket, and you're almost definitely going to have more trub in some, if not all of your bottles this way.
