WHDLoad has a generic Workbench 1.3 or 3.1 install. You could modify that by hand to run productivity apps. I've found it to be a tad buggy, but it's probably something the devs can fix with the right bug reports.
Anything in particular you want to run?
maybe that would be good for the Newtek Demo reels...
I have never been able to get those to run 100% correctly on my A1200.
