Use WLED to controll and configure the HDMILIGHTv2

Hi all
I have done the project hdmilightv2, link is here and , It works well, but now can only change colour with the video, so I want to integrate the function into WLED as a usermod, in the usermod, I need to set the left, top, right and bottom pixel number, after save, it will use uart to send the number to hdmilightv2, also when next time power up WLED, change to usrmod, it also automatic send these pixel number again. when WLED change to othermod, it also work correctly. BTW, I will add a switch for WLED and hdmilightv2 to controll the pixel strip led. So can this workable, or could anyone give some advices, Thanks
