Whenever this comes up I keep figuring it'll be enough to have a Commander for the OP (so WFC Leader with a bigger budget, and Motormaster/Armada Op have shown what they can do with "combine with trailer" situations) and Leader for the Armor Buddy (Godbomber, God Magnus). The RID OP/Fire Convoy trailer doesn't even have to be Superpants or anything, just break apart into armor bits as well.
And the Armor Buddies are basically big Weaponizers of their own, and Godbomber and God Magnus don't have an inner robot situation going on (unlike WFC G1 Magnus) so that's less to engineer. Gauntlets, boots, torso with stow-in head and standard articulation, accessories.
I mean, I don't think I'd ever try to sell people on having this rather than the HasLab set, but it seems doable if one is open to compromises at retail price points (and I'm a Transformers collector, I have a degree in that.) They'd be smaller, of course, at the least, but that's kinda preferable to me.
