I can see your point here, but... when scouting, you can already look for two sorts that will give you an idea about their skill set and whether or not your scouting a swing player or not. First, you can maybe get a little bit of an idea of their skill by looking at their stats (FG%, rebounds, TO, blocks, etc.). Yeah, sure, this is pretty weak, but could give you some indication, particular when you look at the stats in light of the second indicator, which is position the player is actually being played at. For example, if you are scouting a team that plays a SG at SF often, it's a good guess that this SG has some decent skill balance, perhaps at RB or IS or along those lines, otherwise why would he be played there often? (You should check to see what other options that team has at SF, too.) Or maybe there's a SG who plays a lot at PG, which could indicate that the player has solid PG skills (PA, HA, etc.) to go along with the traditional SG skills. Or maybe this player has been getting PG training and is on the way to becoming a player with solid PG skills. The point is, I still don't see the need to potentially confuse us with swing player categories when the benefits seem marginal and unnecessary.
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
