I am assuming you are from the sub-continent and so was I originally as Hanafi Madhab.
I have done the mixing and matching up as I saw fit contrary to what the person in above is saying.

The people who say "cant mix-match". Welp, within the same Madhab multiple opinions exist whereas a opinion of these might be same to a opinion from another scholar of other Madhabs.
And this is the video of the prayer that I follow now.
