If I ignore the parentheses above, the answer is yes.
If I include the parentheses, I have to ask: what does QMetaMethod have to do
with the new connection syntax? I'm not sure you understand what you're
asking.

You need to cast the pointer-to-member-function to the type that you want. You
do that via static_cast or by assigning it to a PMF variable.
void (QComboBox:: *signal)(int) = &QComboBox::currentIndexChanged;
connect(comboBox, signal, this, &MyClass::doSomething);
