These are some I really enjoyed and would recommend to watch:
Ex-Girlfriend Club
Hotaru no Hikari
Bride of the Century
Legal High
Rooftop Prince
@Levee
Angry Mom
Bad Guys
Cruel City
Missing Noir M
She was pretty
Bridal Mask

Boku no Tsuma to Kekkon Shite Kudasai <- sounds interesting, but I haven't seen it
I only saw two dramas from your PTW list but they're geat so I would recommend them anyway :
- Coffee Prince : a classic for gender-bender fans, one good point s that the girl can really look like a boy with her hairstyle and voice in this drama.
- The Moon that Embraces the Sun : very beautiful romance set in a period drama. No gender-bender in that one but the princess pretends to be a shaman.

For recommandation on my PTW list, please max 3 ^^
Death Note
Thousand Years of Love
White Christmas
@SilverCloud

GTO, Innocent Man, Yokai Ningen Bem, Shark (KR), Buzzer Beat and Falling for Innocence ^^
@Nocturna
