What will happen when mixing Clindamycin, tretinoin and hydroquinone in one toner..?

I am using toner mixed with clindamycin in the morning at tretinoin+hydroquinone at night.. Its kinda pain applying diff. Medicine everyday so i was wondering.. "What if i mix the clindamycin, tretinoin+hydroquinone in one mild toner?" So that i don't need to use diff medicine every morning and night.. Will it be okay? Incase you don't get it.. What im saying is "Can i mix this 3 (clinda,treti,hydro) in just one toner? (Liquid) ?? What will happen?
