I am off on holiday next week, so I will give it some more thought when I get back, but my inclination with 12 entrants and perhaps 24 cars is that 3 Events might be too much ?
So perhaps a straightforward Revoslot Event and a non Revoslot car Event is sufficient.
And the non-Revoslot Event split into GT1+LMP cars as one class and the  GT2 cars as a separate class just like the Revoslot Event is planned to be.

The other thought as this looks at the moment like a small field is to revert back to doing this later, after the RoadRace is finished which might attract a few more entrants, starting in October instead of July. 
Perhaps running the two simultaneously was not such a good idea ?
