ubiquitin
I don’t think there is such thing as a minhag not to do something mentioned in the gemara and shulchan aruch without any machlokes. What happened is that some of the items mentioned were not availabe in Europe in previous generations, so they had to do without, This does not constitute a minhag, and there is no doubt that nowadays everyone should eat all the simanim that are obtainable.
The carrots were a substitute for the unavailable rubiya, because it had the SAME meaning in yiddish, but there is no indication that one should search for NEW meanings and simanim in ones current vernacular.
If you’re creative with your puns, there is almost no limit to the amount of “simanim” you can make up.
Here are some you might like:
