1 1/2 weeks post op revision rhinoplasty. Will my nose shrink?

At  less than 2 weeks after surgery your nose is swollen and so it is too early to judge.  However the profile will not change dramatically.  Deprojecting the tip requires specific surgical maneuvers. Your only option at this time is to wait for the swelling to resolve and reevaluate.

although some of your tip issues may be because of early post operative swelling, the obtuse angle of your profile and over-projected tip will likely remain... these are specific anatomical issues that require directed structural surgical maneuvers... the limiting factor for revisions is partly time to allow swelling to come down but mostly the suppleness of the nasal skin as this is what permits safe surgeryDon’t rush and limit your search to rhinoplasty revision experts who have been in practice a while, have a practice focused on rhinoplasty and a propensity towards revisionsGood luck

With just having had the cast removed, you definitely have a lot of swelling present.  I counsel all of my patients that changes can occur in the nose up to 1 year from the surgery.  Additionally, I like to follow my patients long-term as the swelling resolves.  Factors that contribute to the edema include primary vs revision, skin thickness, rhinoplasty technique, surgical maneuvers, activity levels, how one sleeps, etc.  For you, I anticipate that you will see considerable change over this first month.  I recommend that you keep in close contact with your surgeon and attend all postop appointments.
Best of luck.
