Seems like you could very easily continue the material you use for the notch out to the end rather than the stock frame. It would be very easy at the same time to set it up for a different tank too....

I realize that for using the stock rear suspension setup, the trailing arm crossmember location is probably a key factor, but is there any reason that couldn't be just slid forward?

Search board member XXL's threads. He did the back half frame like you're describing. The trailing arm c.member is moved forward when cutting a lwb frame down to a shorty.
