Hi mke,
It seems the first thing here is to put the horse before the cart (so to speak).
I understand why you may want a collection of stylus sizes to fit various 78 records. So the question is: will you do that with multiple cartridges or with one cartridge body which accepts a range of styli to be fitted?
That answer can guide you in selecting an arm. With the former you will certainly want one with interchangeable headshells, with the latter it could be fixed or interchangeable.
Then you mention arm mass. I thought the Shure V-15 series worked best with low mass arms? Check me on that. Anyway, having one cartridge body with multiple styli would make mass matching easier.
Also accommodating 16" records, will a 10" arm allow proper alignment or is a longer arm needed? That should help narrow the search.
Lastly, are you familiar with the resources at this site - https://www.esotericsound.com/CartStyli.htm
Not only do they offer a range of 78 styli, they also have reasonably priced EQ units. Given the variety of different EQs utilized with 78s (essentially all prior to adoption of the RIAA) that will be critical if your ADC does not provide that function.
Good luck with your project. My own needs for 78 playback were far simpler.
