You cannot put a strat pickup in a standard tele bridge,it won't fit.
There are different kinds of pickups for different tones---when Leo Fender wound the strat pup,it was going into a plastic (bakelite) pickguard and not a metal bridge.Also,he was looking for a new sound.
To me,the whole reason to have a tele is to have THAT sound.To put a strat pickup in a tele bridge would be a real expense and kind of defeating the purpose,IMHO.You could have a tele pup wound to strat specs,but....
I've always been rather traditional with strats and teles,keeping them stock (except for the odd itch I've had occasionally).
