Probably.  invokeWithArguments (which is the final name) predates a working invokeGeneric implementation, so it might be able to build on top of it now.  In any case, there is no reason to have an oversized method.  Internally, the call should jump through MethodType.invokers.varargsInvokers.  That would make the method inlinable again.  And the compiler should (though it doesn't presently) bet that MethodType.invokers.varargsInvokers is a stable value.
