I agree that the biggest downside is shutter noise during the ceremony (battery capacity is also a real issue). The least expensive solution - while attaining the two body requirement mentioned by others - is to add the K-01 with a viewfinder loupe (preferably the Perfect version allowing for flip up viewing). The K-01 is slow for RAW, but is very quiet due to no mirror slap, great battery capacity, and allows for some light video work if requested (better than the K-30 which lacks mic input, has only a mono mic on board, and the battery drain in video is very limiting).
The reason it can work - at least as a starter pro rig - is the menu system and photo quality (same sensor on each) are a very close match between the K-30 and K-01. Under pressure, the last thing you want is to remember menu differences between cameras.
