These aren't small worlds, they're the exact same size as Hydaelin, plopping them into the Source would destroy ecosystems left and right. You think we did dirty to the Ondo on The Tempest? 99.9% of all sealife is going to get destroyed when you drop (6 reflections x 5-odd continents = at least) 30 landmasses on top of the world, and that's if we're "lucky" and those continents appear on "empty" parts. Otherwise Ishgard will get destroyed (AGAIN) when 3-6 different Kingdoms try to poof into existence IN it.
I'm not against visiting other shards, mind, but the logistics of having them physically appear in the Source is, to quote Yoshi-P "NIGHTMARE"
