Welllll in my mind it might stick to the cake once turned out. Parchment or wax paper has a very different finish that allows it to be removed while warm. I'm not sure a filter would come off w/o tearing some cake along with it. Looks like another project for you or someone to try & report back for all of us :)
if you cover it with cake batter you're fine -- if you try to bake cookies on it it will probably flame up --
