Default Existing Armstrong bracket+25", new 30" OB?

Have an existing Armstrong bracket mounted, it appears to be bracket for a single 25" shaft OB? Mounted is a 25" 2005 Verado 275 right now. With a 4 blade prop, 17P Rev4 it is at perfect height I can do a hard miami vice style turn and no cavitation. If anything I maybe could go up another hole. Have 3 bolt holes can go up on the 275. With a 3 blade prop it cavitates on a semi hard turn. Love the 4 blade prop, gets out of hole quicker, planes lower speed, than 3 blade Mirage Plus gathering dust in garage.

I have the opportunity to buy a 2020 300 Verado with 295 hours, and warranty for another 5 years at a pretty decent price. Already put a deposit down when the lightbulb fell hit, me on bald head....hopefully the cut is not that bad got many scars already up top.

-->Can I mount the 30" 300 on this bracket?! I "can" lol, but will i have the needed height to go up? My gut says no I need a new bracket . I def want a 4 blade prop on the 300 so swapping back to a 3 blade not wanted.

I'd rather not have to mount a new bracket, but if did....I would have Armstrong add extra float out to the second strake . Perhaps have the platform height raised to fit the tabs 2"(perhaps not that may cause other problem) directly on transom versus my shimmed install. course a hermco would be better. I have contacted Armstrong on a custom bracket with extra float.

The pic of the trim tab mounting is not related to the question just thought would should a semi creative solution to mounting short ram electric tabs almost far outboard as can be given the bracket constraints....couple of shims top and bottom.

Thanks!
