Now that the cars have much higher downforce numbers and the tires are wider, it should be reason enough for Charlie to stop being paranoid and let the TRUE WET races happen.
Actually, I´m expecting just the opposite. Main problems on wet races are aquaplanning and visibility. With wider tires aquaplanning is more prone to happen, and visibility will decrease as each tire is evacuating more water, thus increasing spray.
Well, I think aquaplaning has direct relation with the grip that the tyres offer.
And I´m afraid you´re wrong. Grip and aquaplanning are not related. Aquaplanning happens when the tire threads (that´s the correct term for the wet tires channels in english?) can´t evacuate the water in front of the tire. If that happens then the tire can only go above that water, so there´s a water layer between the tire and tarmac, thus the grip suddenly go to zero.
Rubber grip only matters when there´s no aquaplanning, but it does not affect water evacuation of the tire. And obviously the wider the tire, more prone for aquaplanning it is

As for visibility, of course the bigger tyres create bigger spray, but equally, they move out larger amount of water from the track than the past tyres did! That means, cars gain grip faster and as the larger spray would move the water out in larger quantity, the visibility increases lap after lap, as larger spray decreases the water from the track AND reduced water means reduced spray!
If you assume a wet race only because it DID rain, yes, wider tires will dry up the track faster but, what if it´s persistent rain even if it´s light? Much more spray (25% more), and poorer visibility
IMHO wet tires should be much narrower than dry tires, I even opened a thread some time ago asking about wet tires problems, and the general consensus was aquaplanning is also caused by cars floor, not only the tires, but at least the spray and visibility problem would be drastically reduced
Maybe narrower but much higher to move the whole car up... but that would require gearbox changes wich is banned
