Yep I think they would just about survive if you wrapped the stem ends in something wet and could physically protect them.
But I wouldn't discount having problems getting them into Taiwan. If they are not in sight the chances of getting caught are pretty small.
I made some efforts to work out what the rules are - I wanted to take some seeds in. There are some brochures in English issued by Customs (I don't have a copy with me). In true Taiwanese English style, there was sufficient ambiguity in the various places where it mattered such that almost any interpretation was possible. My Taiwanese friends just tell me "no you can't" but on pushing them they say that the Chinese isn't clear either.
I did find this (

Fruit and vegetables seem to be a no-no - maybe you've seen the warning video on the plane. On the hand, I'm sure some of this stuff just means you have to declare it rather than it is banned. If you show the officers in "quarantine" on arrival, they might just take a look and say "no problem"....
