As long as it has an ASP pommel, body, switch, and emitter I think you'll be fine. Things like the Sorceror are pretty dang short as it is. I would imagine that if you can build it in the configuration tool it'll fit, though you may need to do some cram-fu if you're planning on it having sound.
As to the blade, cutting one down with a pipe cutter is fine. I'd suggest using a little glue after you cut it down to make sure the foil stays in place, though.
