Doesn't really matter if there is space for the mirrors. A planar
turning mirror doesn't affect the optical behavior.

Two things to consider: Optical elements are rarely perfectly clean. If a mirror or lens surface is placed near a virtual image, specs of dust may be more apparent then when well out of focus. Also in high power systems dust can produce thermal problems where the light energy is concentrated causing coating or substrate failure.
