Can a 1/4 bend be used at the bottom of a plumbing stack?

I am very limited on space and trying to figure out what would work. The line will then travel about 8 feet and then turn vertical, then back horizontal to connect into a wye combination. happy to answer any questions.

Short answer is No.

Transitions in direction of flow from vertical to horizontal must be done with a long sweep fitting.

Pipe that is at a 45° can be considered both or either vertical or horizontal. Can that configuration help lower the height of a long sweep fitting?

In some rare situations we use a copper DWV long sweep, which has the most compact profile. Not for amateurs.

No. I mean that if your stack is coming down at a 45° angle from plumb out of your slab into the wall, the overall height of the top of the fitting is lower than if it were standing up at 90°.
