No experience of the 20D but I cannot see a problem with using the Lee IR filter.
There are two old threads on IR, check these links.

The big thing to bear in mind with the Lee filter is to ensure that there is no light leak around the sides. I had great results with processed unexposed e6 transparency film. I then tried Cokin filters in my pro shade but had to tape up all light gaps so it was a bit of a fiddle. Remember also that you do need to blank out the eyepiece on these long exposures.
I see Susan is also into this so need to re-read my posts to get my head in gear. Unfortunately my old pc died a death and along with it went all my notes. Pictures backed up but not notes.
