I'll send something in writing.
However, with regard to instability, it depends on the situation.
If the reworking of the constitution also includes a change to allow a second consecutive presidential term, which some fear, then, yes, we will have major problems. If it's limited to changes in the electoral regime, there will be complaints, there will be outcry, but it will not lead to instability. So the issue is whether or not this is used as an excuse to change the constitution to allow two consecutive terms.
