You can try to book the M but I suspect the glitch will be caught and it won't let you book it when the system recognizes you don't currently hold an M2. A LONG time ago I was suspended for medical reasons. I reinstated my G immediately but let my M lapse. I had to do the M1 road test, then 2 weeks later my M2, Only because they had no openings, I then did my full M the next day, as I had no time limitations. But I did have to do all three road tests.
