Replacing a seatclamp on a steel frames bike

I'm thinking about the possibility of removing the braze-on seatclamp assembly, on my steel framed bike, and replacing it with one of these: http://www.edinburghbicycle.com/ebwPNLqrymode.a4p?f%5FProductID=7285&f%5FSupersetQRY=Kclamp&f%5FSortOrderID=%2D1&f%5Fbct=

Has anyone tried this? I thought that the braze-ons could be sawed/dremilled off, before the new clamp is fitted.

Your thoughts are appreciated.
