In my 2023 PB, The transition from electric to ICE is most noticeable from a stop to start transition. I usually have AC blasting and b&o cranked up so it’s not annoying To me. When cruising or coasting the transition from electric to ICE happens without being noticeable. I have to have my cab dead silent or be watching gauge clusters to tell when it happens at a cruise.
The transition from electric to ICE from a stop is rather harsh. Ford really should have coded it so the electric motor would do more work from a stop. For example have the electric motor be able to take the truck up to 20 mph when under light to moderate throttle, start the ICE while the clutch is disengaged then seamlessly transition like it does when cruising. This alone would make a HUGE difference in stop/go driving. As it sits now the ICE will fire up if you put even the slightest amount of pressure on the pedal.
You might be on something. Yes the transition to ice I not noticed when cruising. I believe that even the current system can employ what you suggested. I have a battery monitor and just a few miles per hour from start using the battery is minimal. I have only noticed 1 time that the actual starter motor was used when starting. I really don't know what the circumstances were that required that but every other time it's been started by the generator/electric motor.The transition from electric to ICE from a stop is rather harsh.

Perhaps Ford will use a more powerful radial electric motor and larger hybrid cell in the next generation that will do something like this. as it would significantly improve stop/go fuel mileage losses.
The chances of having fouled plugs is extremely low. The rough idle when charging the hybrid battery is very normal. Especially if you do not have eco-idle active. The ICE is under a significant load if it's not and will lug the engine. With eco idle active the rpm will raise up to 1500 and charge the battery pack up from 40 to 65-70% in about 60-90 seconds then shut off. Even with eco-idle active it lugs a little bit but is a lot less than the lower rpm. You can check to see if this is turned off under the truck settings in the sync system.
There is no shudder with our PB. Though on rare occasion there is a hesitation when starting from a stop.
You can get a cheap cell phone holder, maybe one that fits in a cup holder. Then record as you are driving to capture the shudder. That should [in theory] visually capture the shudder, as it's moment of inertia would be different than the surrounding objects.
Sorry I was not clearer. I have edited my post to focus on what is relevant to your situation.
Another good point - I was just thinking out loud.
In normal mode I don't notice the transition. It's very smooth. I notice the 1st to 3rd gear skip more. In sport mode the off/on engine transition is very noticeable and annoying just like our Expedition work SUV, however in sport mode it shifts through 2nd gear so there's that. I really prefer normal mode thus far. Eco lugs and sport has the annoying start stop. Tow/haul is ok because the engine never stops. Slippery is good for exercising the 4H now and then. It's smooth like normal to me.
