I for one, would like to see 13 cards supported with bminer.  I'm currently running the asrock pro h110 btc with a mixture of 1060's and 1070's and it will not run.  Just hard closes immediately upon launching.  This rig runs 13 cards just fine with efbw, dstm, claymore, phoenixminer and a lot of others, so it must just be a simple fix to enable.  My fees await your fix
