Custom Window Cleaning Platforms

This isn't entirely map mod related, however it does deal with item placement. I was fooling around with Simple Native Trainer and I spawned a window cleaning lift just for sh*ts and gigs. I thought about how cool it would be to set up your own custom window cleaning lifts around the city. To do that, you obviously couldn't load the objects using the trainer - the objects would have to be part of the map. No big deal, because I have no problem converting objects to WPL. I am not, however, accustomed to scripting ... at all. And I realize that in order for a window cleaning platform to work, it would have to be scripted. So my question to all you scripters out there: could you make this work? I'll provide the WPL and an updated gta.dat (unless you're familiar with making pathways and you don't need the gta.dat) and your job would be to get the damn thing scripted. Of course there may be more steps involved than making a WPL and scripting, and if so let me know!
