I don't know what they're like behind closed doors, but from the outside, swapping-over Bonnington and Clear from their current race and performance engineer roles seems like it might possibly be an idea.
Bonno can occasionally sound and behave just a little too much like the McLaren engineers that Lewis left that team to get away from, which clearly aggravates or frustrates Lewis to some extent. Whereas Jock always seemed to me to be a bit of a street brawler, a more rough and tumble, raw-meat, aggressively competitive individual that you probably wouldn't want to tangle with in a pub car park, the kind of guy that Lewis would perhaps better appreciate having on the radio whenever he's locked in a tough battle.
But like I say, I could be miles off.
The other more general suggestion would be that top drivers thought about hiring their own race engineer, like golfers do caddies. Drivers are never certain if the R/E is fully working for them or for the team. It would be their own engineer that would interface with the team's engineering staff, gathered information, made requests/demands, monitored the team's intended program and car changes, offered the driver technical advice, and then ran the radio.
The team would have to inform/convince the engineer of major setup changes rather than bamboozle a driver in a post practice debrief. Of course if the race engineer wasn't doing what the driver wanted/needed, instead of getting annoyed about it, they would have the option to fire and hire someone that better suited their style.
