Not a good idea. Period.
I had 2 goldfish about the same size as yours along with 4 rosy barbs earlier this year, *my boyfriend won them for me at the fair* and I had to do water changes Every DAY!
thats in a 10 gallon! I know the barbs bio load isnt that high so those 4 and 2 goldfish is probably equivalent to your 4 goldfish. if you put them into a 5 gallon, that's going to be atleast 2x daily.
And re-homing goldfish is a very hard thing to do if you want them to go to experienced fish keepers
