It's not the low tyre wear rate that makes wet races boring. No matter what you do with the tyres, the top managers will still very quickly discover the optimum strategy and the status quo will be restored.
In a wet race the cars that qualify at the front have a big advantage and this advantage becomes even more pronounced when the no-refuelling rule is active.
The main reason that wet races are a procession is the lack of DRS.
In a "refuelling allowed" race managers can choose to run shorter and lighter stints in an attempt to gain sufficient time for an extra pit stop. The the fact that their cars are very light means that even without DRS they have an opportunity to overtake heavier cars and pull a gap. So it is possible to use alternative strategies even though the tyre wear is only 1% because it is the overall weight of the car (not the tyre wear) that allows different strategy options.
When refuelling is off, all the cars carry sufficient fuel to complete the full race distance and are therefore running with a very similar fuel load which means overtaking is almost impossible. If a player uses Boost to try to overtake the car in front, most often the leading car will simply use their boost to defend.
I understand why someone would suggest revising tyre wear to force at least one pit stop but IMHO it will not suddenly open up more strategy options in a wet, no refuelling race.
