Indeed, there is several command you can send to the controller, the 0b000000011 is to have the status of all the button/joystick.
So If I understand properly:
- I connect the data pin of the controller on the MOSI pin to use it to send command
- I connect the data pin of the controller on the MISO pin to be able to read
- I send a command via MOSI, and until I receive the response I don't send anything to avoid any shortcut ?
- I receive my response so I can process stuff and be ready to send a new command.
could you be more specific about what the"larger buffer" ? :)

I guess the N64 replies after you've sent the bits?
I'd suggest you just connect SPI MISO and MOSI together, and then send the data via SPI. If you send a much larger buffer than you need, so:
Then you'll be able to use SPI to read the data back in at high speed too.
