I think the best way they could of did it was with the actual models of the primals just smaller. I dont disagree with Egi's though, it still makes primals relevant (powerful) while allowing summoner to exist as a job lore wise. Free Company summons also might use actual primal models, however that works.
I just think this is how summoner will work in this game which I see how it is disappointing to many people but they wouldn't go through the trouble of the Egi's to then implement a "full primal version". A cooldown sure but they wouldn't have done Egi's just to give them full models and Im sure they knew people would be disappointed too but it has to fit the world at least for SE. Im sure someone well versed in the lore can debate it but SE wants to keep the primals fierce and intimidating without turning summoner into a hero class (needing a max ish level character to get the summons)
Its a balance between lore, accessibility, and functionality. I personally don't mind the Egi's, disappointed sure but Ill be okay with it if the job works and is fun.
