Lambda and knock sensor on one UNO

I know that some shields can be used together, but I am curious if this one can?
According to my opinion, there are some pins which are used for both shield like digital output for LED.
If I overdrive these pins, and make correction in code, will I be able to use both shields?
What about SPI CLK, MISO, MOSI, NSS or RX? It would be okay if they are used for both shields?
Thanks.

Hello Strgan,
The simple answer is that you can not stack the Lambda Shield and Knock Shield on one Arduino UNO. The tricky answer is that you can probably connect the Knock Shield on the side using a breadboard, selecting the pins and functionality you require. It would definitely be possible using the Arduino Mega.

Thank you for respone :)
One quick question, did you or someone else tried to connect Bosch 4.2 Lambda insted of 4.9?

I have not seen the need, why use LSU 4.2 instead of LSU 4.9?
According to the datasheet you need to configure the CJ125 by changing 2 resistors for it to work with LSU 4.2, I have not verified it.
