Yes—there are a few workable alternatives, depending on the shoot.

A common option is to use an assistant holding a monopod or extension pole with the light mounted on it. With a normal-height person and a long pole, you can often reach the height needed for full-length portraits.

Another approach is to bounce flash off a nearby ceiling or wall to create a larger, softer source instead of physically raising a softbox or light. This can work very well if the surface is close and neutral in color; colored walls or ceilings can reduce power and cause color casts.

Some photographers also improvise support using a sturdy decorating/painter’s pole, sometimes braced floor-to-ceiling and fitted with clamps for small lights. That can be effective, but only if the pole and clamps are strong and stable enough for the load.

In short: if you only occasionally need the extra height, an assistant-held pole, bounce lighting, or a sturdy extension pole can be practical. Just be careful about stability and weight capacity.
