No.
That's not going to work out, mathematically.

Dear Cinaed,
The costas loop works only with BPSK, QPSK and 8PSK.
Is it possible to change the actual costas loop and add the 16 QAM.

I use the Polyphase Clock Sync.
In the tutorial 7, they use a channel model
Const. Demod -> Channel Model-> Polyphase Clock -> CMA Equalizer ->
Costa Loop -> Demodulator
and put the Constellation Sink on the output of the Costa Loop.
