Default [REQUEST] HTC_IME Sense 5 or 6 porting to Sense 4+

Hi guys!
Anyone known if exist some retro porting of HTC IME Sense 5 or 6 to Sense 4+ UI?
Sense 4 keyboard have so much lags and I don't want to install a sense 5 or 6 rom because for me Sense 4+ is the best UI.
Can some one help me?

Thank you
