I can't see any problem with it at all. There are lots of 3D application that support lots of different formats. Ultimate Unwrap for instance. I think the makers of the 3D apps are just happy to have people make converters for them. If you do a SketchUp to Blitz converter, it means SketchUp will attract more Blitz users, which in the end means more sales for them. It's a win win situation.
The only exceptions I know of are GIF and mp3. The GIF patent I think has expired, but it meant GIMP couldn't include GIF support. And for mp3 you need to pay for any app that supports the format, I believe this would include something like and ogg to mp3 converter. But most companies are not so asinine about it, so you should be fine.
