91 prelude motor question...

i was in the junk yard today looking around for various parts etc... i popped open the hood of a 91 honda prelude 2.0 Si . i happened to notice that it has a B20A5 motor in it (DOHC non-vtec)... why doesn't anybody do a b20/vtec motor with this? all b-Series motors have mostly interchangeable parts right? why couldnt you slap a b16a head on there along with some b16a pistions just like a b20b or b20z motor? anyone tried this?
