Select smallest file from 2 files with same file name...

I am a digital scrapbooker and Hazel has been a great tool for me to manage all the digital files I purchase and download. One task I am still doing manually relates to files that I typically get that have the same file name but either the PSD or TIF extension. Since my software can read either type, I want to identify the smaller file and move it to the appropriate folder. (it would be a plus if Hazel could either trash the rest of the folder or label the folder so that I know it has been processed and has files that can be deleted).
Any suggestions for how to accomplish this?
Thank you in advance!
