Don't bother, even directly converted from Paradise to New, the sound is overly muddy and terrible. The bass being removed was the next best thing when you see what a direct conversion gives you imo.
To answer your question, you can use AcbEditor to extract the cuefiles from Paradise, and then use deretore tools with the HCA key to re-encode the wav file to New.
The best way would be to get a high quality MP3 or FLAC version of the songs and edit them in Audacity to match the Chunithm version beat-for-beat. Then re-encode this version into New and you've got quality that knocks everything else out of the park. The only problem is how long it takes to do.
