+In this specific example it would indeed be easier.
+Unity is not really that simple unfortunately.
+
+The main problem is that Unity does some 20.000-100.000 mono_runtime_invoke calls 
+every second depending on the game.
+
+If i wanted to do this indirection through managed code i would have to convert all our 
+code that uses mono_runtime_invoke to call the managed ridrect method. Which then calls 
+Invoke from managed code as you described.
+
+In Unity however we do not know the class or the method name at compile time.
+I presume there is some way to directly pass the MethodInfo from unmanaged code to the 
+the method that does the redirect. But of course the MethodInfo would first have to be 
+allocated.
+
+Parameters also would have to be boxed, and a MonoArray would have to be allocated 
+instead of using the usual mono_runtime_invoke parameters.
+
+It seems that this would make invokation of our methods around twice as slow. So thats 
+not very good. This is why, i want to switch domains from unmanaged code.
