I got your question wrong. In maps.idx you can only swap whole levels, not single objects. The structure of the idx file is: identifier, position in wad file, compressed file size, uncompressed file size, compression type: b (byte), w (word) or u (uncompressed).

To change single objects you have to find out which line in maps.idx is "So the Adventure Begins". With the position after the comma you can find out where in the wad file this map is stored. There you can look for "SmashBlock" for example and try to change some bytes.

I told you, it's harder that swapping whole levels :)
