Will this work for RF?

Tank is heavy roughly 27 ling x 15 dia. Idea is put the two 4" pipes toward back. Cut btm one off and seal. Cut flange from top one and extend if needed. Concern is will stack at back close to end work as an RF. Really havnt seen many smokers at all with stack on back close to end, mostly centered on end.

I'd find something more suitable.27" is too short for all the work involved.
