A 4th-level Earth Tremor with Augment is really funny. With 6 secondary casters (Who do not need to expend a spell slot), that's a 5280-foot grounded emanation. It doesn't damage objects or structures, but it does have a chance of harming creatures, so if you cast this in like a village or small town, you'd probably kill most people and animals there if you're lucky, while also causing massive difficult terrain.

Augment a Dimension Door to 1500 Feet! The secondary caster doesn't even have to expend a slot for it; they could just hitch a boosted teleport ride! I'm unsure how Distant Spell Metamagic works here. Idk if you double the spell's range after or before Augment is taken into effect. If it's before, that's a 2000-foot teleport, if it's after 3000-feet!
It's crazy that you can do this without having the secondary caster have to use concentration or expend a spell slot- you just gotta be able to get a turn before the primary caster loses concentration.
