The times I've dehydrated my chillis included a number of different types from tiny little Thai Birdseyes up to quite large Lal Mirch and several in between. Some quite fleshy and some very light, hence the time taken and the need to check and remove some as they were done.
I see nothing wrong with cutting larger ones up, removing seeds etc and trying warmer and faster dehydration. The main thing is that they need to be completely dried or they will spoil.
