Most of the mags historically that people have/mod are short-short cases, like 6 ppc, 7.62x39, these all have the same parent cartridge, the 220 russian.
The steel 6.8 spc mags have worked for some, as an AR mag, it has similar feed lips and pretty much the same follower design, just a different color.
I think the issue you will find is how to reduce the width between the feed lips, for a slightly smaller diameter case than the 308 family.
Amend2 made some AR style mags that were single feed at the top and double stack down lower, they didn't take off very well, the single feed AR-style was just placed over on one side so it would still go to the feed ramp ok.
