the "business case" for a varied fleet is that it might cost less to have a high/low mix to use according to the situation.
I'm obviously simplifying here, but it's like having a an electric car for your daily commute and a larger gas car for the occasional longer trip.
If you were to have the electric car only, you wouldn't be able to perform the occasional long trip "mission". If you have the big gasoline car only, your operating costs are very elevated.
Of course you now have two different replacement parts, maintenance procedures, insurance, etc., So you have to run the numbers and gaze in the crystal ball.
Whether a high/low mix makes sense depends on unpredictable things like "how many confrontations with near-peers will i get into" and somewhat more tractable metrics like CPFH, engineering NRE, gas $$, training, etc. But the point is, unless you can run those numbers, you can't say it doesn't make sense.
I could come up with a scenario where in the next thirty years there are only low-level skirmishes and they're being flown by F-35s plinking bombs from straight and level, something a Cessna Caravan could do (I'm exaggerating of course).
I'm all for a high/low mix. It would be nice if they looked around and dual-purposed an airframe that would already be in-theater. Adding forward-based logistical support for "another" airframe is a significant complication that isn't necessary.
This doesn't have to be an "Air Force" only solution. Although the AFSOC has been working on upgrades for their CV-22's for the last few years that are in the pipeline already (~Q3/21). These upgrades can be extended to the Marine Corp and Navy.

The MV-22 is a possibility. The Marines are all-in on this airframe. Maybe it's time to look at a block upgrade of avionics, engines and armor for their fleet. They will also be backed up with 35B's.
Why not look at the the UH-60 replacement programs?
The V-280 or the SB-1 look like suitable platforms. Adding mission based weapon systems is not out of the question.
Still think this needs be looked at as a gun/bomb/missile truck. The AFSOC CV-22 upgrades are in the pipeline already. From the above article, "The Naval Surface Warfare Center Dahlgren Division in Virginia is conducting a study to determine the optimal weapon for the V-22 and where that weapon should be placed in order to maximize coverage of the aircraft. The study, which began in 2015, is expected to continue through 2018. It will focus on guns and precision-guided munitions, according to Naval Air Systems Command."

From http://nationalinterest.org/blog/the-buzz/the-us-marines-might-have-found-secret-weapon-it-had-all-18747
"NSWC (Naval Surface Warfare Center) Dahlgren explored the use of forward firing rockets, missiles, fixed guns, a chin mounted gun, and also looked at the use of a 30MM gun along with gravity drop rockets and guided bombs deployed from the back of the V-22. The study that is being conducted will help define the requirements and ultimately inform a Marine Corps decision with regards to armament of the MV-22B Osprey."
This is not a complicated problem that needs a 100% solution. Continue support of the A-10. Upgrade it as necessary. Marine Corp already needs upgrades of their MV-22B fleet. They're availability for B's is too low (~75%) today. Integrate the AFSOC systems, engine upgrades (from C models) and weapons into the B upgrade process. Ensure these capabilities are included for future block upgrade road map for UH-60 replacement program.
Don't acquire a new airframe when there are existing airframes that require upgrades today to boost combat readiness rates.
Don't acquire a new airframe when there are existing airframes that have upgrades in the pipeline that just need funding.
Don't acquire a new airframe when there are existing airframes that already have in-theater logistical support plans.
Don't acquire a new airframe when these upgraded airframes will provide the capability required.
Just my 2¢.
