I have, on a couple of occasions, roasted the same coffee to different degrees of roast and then combined them.  It does give you a different profile.  I have also roasted some in my Behmor roaster and some in my Nesco roaster and then combined those.  That too yielded a different flavor profile.

I'm just sayin'

I've been thinking of trying to blend my own coffee as well.  I may have to try next week mixing some roasts up and seeing what I come up with.

 

@Neil so you find mixing them after roasting is better?

Yes. You have maximum control over each bean's flavor profile when you blend post-roast. This is not typical of commercial roasters. Most roasters will pre-blend the beans and then roast the blend to the same roast level. This does not give you the flexibility to bring out the best in each bean and to then blend those flavor profiles, but it is admittedly easier.
