Sounds horrible, think of an original name without either trance or core in it that way you'll have a chance of selling it to a new generation.
That was the name M8 used years ago for the stuff Bill 'Daniel' Bunter was playing which was in the end HARD HOUSE!!
Trancecore has been around for years... its like trance with erm a hardcore beat.... but hard house has progressed massively since its birth (trade gave it a huge face lift years ago). Just like promise has aided the evolution of trancecore
