You can, but you may have two problems:
1) The colors may not match what you want. Weathering powders are specifically designed for modeling and have the appropriate colors. Pastels may have equivalent colors, or they might not.
2) Weathering powders have a binder included to get them to stick to the model. Pastels don't. You'll need to seal the model with a varnish layer either way (unless it's a pure display piece that will never be handled), but the binder makes it a lot easier to get the powder to stay in place long enough to seal it. It's possible to work around this and maybe it fits the style you want but for most people it's probably just a significant increase in frustration for a very small cost decrease.
