You are fully right. Changing the iginition without some knowledge might end badly.
Luckily the FZS ignition is not that advanced as in modern car engines. It is only a simple electronic switch with a timing map on top. The move towards single coils came with the demand for sufficient spark power with increasing revs and lean fuel mixtures.
Here are some pictures about what I'm talking.
First is taken with the original FZS1000 coils.
Second one is taken with R1 coils and additional driver stage. You see the advantage at highest revs. You might make use of the better spark in case you have modified the carbs an/or exhaust. Gives you some more room with the fuel air ratio.
For stock configuration I don't see any significant benefit. But would be worth a thought if you are anyway on the way to change coils because of a defect. Failures in coils are tricky to detect. A new one gives you confidence.
