I'd like to spread the rear triangle on a '84 Schwinn Mesa Runner to accomidate a more modern wheelset and components.
As you can see from the photo below this bike has a bolt on derailure hanger.

I'm concerned that I will not be able to adjust a replacement derailure to compensate for being further from the rear cassette (than it would be on a bike with an integrated derailure hanger).
Is my assumption wrong?
I've considered using a Shimano Tourney Deraileur, but want to upgrade to an 8-speed (and I've heard my share of negative opinions on Shimano Tourney Deraileurs).
