That's easy if you can do the math. Record the 4/4 parts and the 6/8 parts individually, then have the producer splice them together. If done right, the song will be seamless and the feel will remain in tact.Yes we could, but the problem is that a lot of our songs change time sig during them. We switch from 4/4 to 6/8 and back again. I think it could be possible to use a click for some songs and I would be interested to try but the lead singer/rhythm guitarist is really against it and believes it would kill the feel. You may feel he's making excuses not to learn how to keep to a metronome and you can make of that what you will. I've always believed however that the drummer's job is not to keep the time, but to make the beat. Keeping time is the responsibility of the whole band.
