2nd generation Wyeast Belgian Saision and Brett B

I made a Wyeast Brett B and Wyeast Belgian Saison beer about one month ago. I am going to let it age to get a more pronounced Brett flavor.

I am interested in making a new Saison wort and pitching it directly on the cake. This time I am looking to make a quick Saison one month or so. I am going to rack into a keg, keep cold and drink. I am basically just trying to save money by reusing this cake. I don’t care if I get the big Brett characteristics this time around.

Question: Will this work? Addition advice? Personal experiences?

Thanks
