Maybe 9 months ago, I read that someone did exactly that-much efforts, a fair chunk of money spent (even though he already had a TL), and very little tangible rewards, as the Strom is designed to work well with the wheels it has. Perhaps a bit of research into better tires for the stock rims would be in order, along with lower bars, cut down the stock shield (which looks great!), and a better sounding muffler. OR... a used TL for your garage (along with the Strom, of course!).
I understand what you're saying about the stock seat. One of the first things that I did on my Wee was to have Rick Mayer Saddles make a custom seat for my butt on my bike. 600 mile days are now no problem.
