You can try and make it work, but not sure it will:

I tried manipulating the answers with a Business rule. That corrupted the whole Survey.. so no luck there

Have the hyperlinks behind your emoji icons point to a custom UI Page that accepts a parameter indicating which icon was clicked. In the code of the UI Page, update the value of the corresponding question(s) in the relevant assessment instance and then redirect to the assessment page. When the assessment page loads, it should automatically identify that some questions already have answers in the database and preset them on the form.

All you need is use a GlideRecord query to get the record you want to update, set the necessary value and save it. Documentation for the GlideRecord API is available here.
