No, that won't be offered as an option.
Your choices will depend on whether you're joining the Army, Navy, or Air Reserve.
Army Reserve, you have 2 options:
Navy Reserve, pretty sure there's just 1 option:
Air Reserve, also has only 1 option:
Army and Navy Reservists can on rare occasion attend a full-time Regular Force BMQ at CFLRS, or occasionally with the Air Reserve. This is fairly unusual though, as most reservists have no need to attend the full 10 week course. The 10 week course includes a lot of administration and other information that is either not relevant to the Reserve Force, or is already taken care of by the Reservist's home unit prior to them attending BMQ.
