Ive considered it, but ultimately the tank you made is perfect. The problem for me is that I lack artistic vision. When I first mounted the tank to the backbone it just seemed rediculously small to me, but once more progress was made on the bike I began to realize the tank was actually perfect.
Had I been able to envision the bike in my head I would have realized that from the start, but I had no idea what the bike would look like until recently when more of the parts were mounted. At this point I'm completely happy but back then I couldn't picture it in my head.
I think that's what makes a great artist. The ability to look at a canvas and create an image in your mind's eye. I just can't do that. It's a talent I envy.
