I have no specific advice, but I urge you to pursue the project. I've done something similar and I'm really enjoying it. It's a small 3-way with open baffle in the midrange only, covering 400Hz to 8kHz and monopole LF and (super?)tweeter. The 3" Tang Band is not going to break any SPL records but they suit my needs for this setup. Working on a version 2 now.Ok, noted. That is good advice. Yeah, I need to convince one of my friends to buy a Linkwitz Mini so I can borrow their minidsp... Lol.
Yes, you're right that I was a bit silly to suggest a particular driver without any modelling or citations of other drivers I want to use. I will rephrase my question:
Are there drivers available which can play down to 550Hz in a moderately sized OB and up to 4-5KHz with wide and uniform dispersion?
Intuitively, I feel a speaker around 4" would be the best in between, but I am absolutely open to suggestions. Does anyone have any drivers recommendations I can put on my shortlist to model? Thanks!
I documented the 1st prototype here, I've made a lot of progress since then:

My point is that the VC diameter sets a driver's pistonic polar response upper limit. A stronger magnet allows a heavier mass for a lower Fs/whatever or a wider acceleration BW up to its mass corner, so just depends on the needs of the app.The 10F 8414G10 has a 19.4 mm voice coil, does it help if it has a neodymium magnet structure? The 8414 is meant as a full range driver and has an open basket beneath the spider.
The 10F 8424G00 has a 20 mm voice coil, basked closed beneath the spider and meant for use as a midrange driver. Different (bigger) magnet too and more x-max (2.6 mm vs 2.3 of the 8414).
Are there drivers available which can play down to 550Hz in a moderately sized OB and up to 4-5KHz with wide and uniform dispersion?
FWIW a 550 - 4 kHz driver eff. [Sd] calcs to ~42.8 cm^2, 550 - 5 kHz = ~34.24 cm^2.
