i do immediate on premolars often, especially on first premolars.
I would stay little more palatal since it is easier to graft the buccal jump gap than the palatal.
Take it out of occlusion at CO and Excursion.

Thank you for posting this case. Whether or not you place immediate implant, I recommend making a temporary crown at some stage of treatment. HiOssen does have the best array of healing abutments on the market in my opinion but in an aesthetic area with an aesthetically demanding patient, there is no substitute for temporary crown for building proper emergence profile.
You will end up with a jump gap likely both on the buccal and palatal aspect. You can graft both B and P with allograft. I use cancellous bone for faster turnover but cortical bone or 50/50 mix will work too (just takes longer for it to turn over).
Every temporary crown needs to be protected (I give an Essex stent with that temporary crown cut out) and patient compliance especially for premolars is vitally important.
