One of the issues I have with the GS wheels is that to get them looking good they have to be cleaned up specially and/or powder coated. (black rims are very sexy). If you use another type of wheel you will most prob get a shiny rim & hub to start with, & respoking them won't be an issue if they need doing vs the stock spoke pattern. Small issue really but one that I think about every time I look at my manky spokes.
Keep it going.
If I came across another project I would seriously look at raising the motor & raising the ride height of the bike (as well as stripping everything off it.
