No more of this Roman Empire Bull!
Well, our day names come from Old Norse/Germanic sources. Since English is a Germanic language maybe we should go with modern versions of their month names as well. Then again, most of the old names en with "-monath" (month) so that would be almost as bad as having all the "-embers" together at the end of the year.
What about the French month names that they came up with during the French revolution? These are a mouthful for non-French speakers, but they look nice.
The Republican calendar year began at the autumn equinox and had twelve months of 30 days each, which were given new names based on nature:
Autumn:
Vendémiaire (from Latin vindemia, "grape harvest") Starting Sept 22, 23 or 24
Brumaire (from French brume, "fog") Starting Oct 22, 23 or 24
Frimaire (From French frimas, "frost") Starting Nov 21, 22 or 23
Winter:
Nivôse (from Latin nivosus, "snow") Starting Dec 21, 22 or 23
Pluviôse (from Latin pluviosus, "rain") Starting Jan 20, 21 or 22
Ventôse (from Latin ventosus, "wind") Starting Feb 19, 20 or 21
Spring:
Germinal (from Latin germen, "germination") Starting Mar 20 or 21
Floréal (from Latin flos, "flowering") Starting Apr 20 or 21
Prairial (from French prairie, "pasture") Starting May 20 or 21
Summer:
Messidor (from Latin messis, "harvest") Starting Jun 19 or 20
Thermidor (or Fervidor) (from Greek thermos, "heat") Starting Jul 19 or 20
Fructidor (from Latin fructus, "fruit") Starting Aug 18 or 19
The month is divided into three décades or 'weeks' of ten days each, named simply:
primidi (first day)
duodi (second day)
tridi (third day)
quartidi (fourth day)
quintidi (fifth day)
sextidi (sixth day)
septidi (seventh day)
octidi (eighth day)
nonidi (ninth day)
décadi (tenth day)
