There are huge engineering challenges with making a modular, quick caliber change rifle work at all. Just look at the Masada/ACR, SCAR, XCR, etc.
The caliber change kits have been long in the waiting for all of those designs. To change to a totally different parent case and action length within the same action now requires some way to address bolt travel differently, like when going from 5.56 to 7.62 NATO. Easier said than done.
