It might just be me but describing the depth of an incline press made me think for a second (I assume from the BB?) I'm going to describe it a little differently... The in-congruent position of the shoulder is at ~60^0 Abduction and 30^0 Horizontal Adduction. (Start Arms at your sides, jumping jack motion out 60^0 then arms to the middle of the body 30^0) Which means it puts the most stress on the ligament structures of the joint. I think the most potential harm for injury can come from not having adequate back muscles to stabilize the scapula during the movement if you are doing a incline bench press forcing the rotator cuff muscles to be over strained in stabilizing the joint. The question by full ROM are you talking but full extension of the lift or Full ROM of the shoulder in Abduction like doing a Military Press.... I agree with /u/narf007 too the DB could be the way to go if worried about instability.
