Reinstall 4809, go copy the screenset out to somewhere, install 5153 and add the old screenset to it.
You COULD do this with directory renaming, too. Rename Mach4Hobby to Mach4Hobby_5153, install 4809 which will create a new Mach4Hobby directory. Copy the screenset you're interested in from 4809 install. Name folders back, Mach4Hobby to Mach4Hobby_4809, Mach4Hobby_5153 to Mach4Hobby. If you have other customizations, you will need to take those into account, too.
