If the Pramac team gets back the current specs like the factory team (in 2023, as you wrote, Pramac and the factory team had the same specs, I don't know about possible updates during the season, and all the other teams had 2022 specs), all the teams with the 2023 specs will probably get very competitive and tested bikes.
This is still possible to happen, but as seen last season or the 2023 season, Ducati itself always develops its motorbikes every season, so they also have a special agreement regarding providing motorbike specs when purchased by their own customer teams, as in three satellite teams owned by Ducati this season where Pramac gets a share of motorbike specs that are no different from the factory motorbike specs. So there is a possibility that something like that will happen again next season where the Gresini team and Rossi team will get the Gp23 spec and the Pramac team will get the Gp24 spec, although during the test there will definitely be many changes made by each team.
It will be very difficult for Marini, Honda did not achieve much with Marc in the last 2 years and development was probably the reason why Marc changed. Marini won't be able to have much influence on the development of the current Honda for next year, so hopefully Mir has done some good groundwork.
Mir also does not have any further ability to develop Honda motorbikes during the 2023 season even though Honda itself still has high hopes for Mir to make Honda motorbikes more competitive because Santi Hernandez will handle Mir next season. Meanwhile, Marini will indeed have difficulty understanding Honda motorbikes, but that doesn't mean we have to immediately judge him as bad because he has just tried a Honda motorbike.
