We have a feature request for the ability to plan backwards from a task, a.k.a. "as late as possible". I'll add another vote to it for you.

There is a way you could work around this by locking the start date of the second task, and setting up the dependency with lead time as before. When you get a violation, move the pre-requisite earlier, instead of following the violation's suggestion of moving the dependent later.

This wouldn't be very simple though. :(
