Hostile Juxtaposition

[subway rat]

I want to use this spell to make a baddie fall to his death.

Here's the text::

You create a dimensional link to the target creature. When attacked or the subject of a spell that deals damage to you, you can spend an immediate action to cause yourself and the target creature to teleport and switch places. The target then becomes the target of the triggering attack or spell instead of you. If you fail to teleport out of the area of an effect, that effect might still affect you. If the target creature cannot fit safely into the new space without squeezing, or you try to teleport the target into an occupied space or a space it could not normally stand within, the juxtaposition fails. Further, if the target is unconscious or dead when you attempt to switch places, the juxtaposition fails. Once you have used it to teleport once, this spell is discharged.

The spell has a range of 25ft + 5ft per 2 caster levels.

Let's assume I'm flying. Now, if I successfully cast the spell 25 feet away from the ogre, then fly straight up 100 feet and cast magic missile on myself (not in the same round), will we still switch places?

The spell has already been cast within range, but I am now out of range. Also, there is the clause about the spell failing if it's "a space it could not normally stand within". But then that brings up questions about whether you can even use this spell to get out of a pit of acid.

Your thoughts?

The range doesn't matter once the spell's cast unless the description says it does. I don't think you can teleport an enemy into mid-air nor into a pit of acid (unless perhaps it can stand on the bottom) due to the text you cited.
