If by "little modification" you mean finding a very hard to find compound slide and then machining a new base plate and T-nut for it then yes.
I considered retrofiting a QCTP to the existing shoptask riser block thingy, but then you would have no compound. I considered retrofiting the shoptask compound but it has an almost useless range of travel. About an inch and half if I remember correctly and no real provision to poperly mount a QCTP. That's a problem if you want to taper anything very much since the ST has no taper attachmnent.
So, I opted to scour ebay for months untill I found a compound that suited my needs. The first one I bought was off an old southbend 10" lathe and turned out to be too small...for my liking. It's similar to the original ST compound in size. Finally I found a clausing compound from a 14" lathe. This one is a bit big but has a usable 3" of travel and I can hold a 3/4" tool and still make center height. The toolpost I chose was a KDK and these were fairly common on ebay last time I checked.
Check out the link on my site under "machining projects/clausing compound base" for some pics of that project. I highly recommend it, very much worth the trouble.
