Sure, the picture I linked is of me piercing an aquifer within ~1 month of embark with magma generated in a reaction and dumped into a pit in a particular location using minecarts.
In Orc Fortress you can't actually embark with the capability to do this; it is a rare random drop in the mod, and requires a lot of steel even once you happen to get it. But in your own version you can make the building requirements and reaction reagents whatever you like.

Many players just disable aquifers anyway, or don't embark on site with them, so, /shrug. Mods are about fun, which for experienced players is mostly about adding more challenges. Once you've done it a few times I wouldn't say that dealing with multi layers of aquifer cancellation spam is either challenging or fun. If it's a thin aquifer or in stone it's easier to do the old fashioned way in any case.
