Will there be support for a box collision component for character classes instead of capsules?

I am currently using 4.12 for a side-scroller - but any time I go slowly towards an edge I end up floating because the capsule component is rounded at the bottom so I end up floating on the edge of the platform. But if I end up making my capsule too thin so that doesn’t happen I end up clipping half of the body through a wall? Is there something I can do about this?
