SN 2020qxp is now also confirmed as a Ia and the classifiers suggest it should be near maximum light in which case it should in theory be  approaching  ~mag 11 excluding extinction in the parent galaxy.  They also compare it though with SN 2007on which was classed as “transitional” (ie with a luminosity lower than normal for a 1a but more luminous than sub luminous 91bg-types).  SN 2007on was considered a good candidate for a white dwarf merger supernova event eg
