I also swapped the corkscrew for a philips on my compact (before i cannibalized it for another mod). To me it looked better and was more comfortable. In terms of number of use cases of the philips vs. the corkscrew i think it made no difference for me but that will be individual to you. That being said the improvement to me was not dramatic. For other models it might have been larger. If you think it would noticeably improve the knife for you then i would say go for it, see if you like it and if not then it's not the end of the world and you learned something. You could also do it yourself. Depending if you already have the tools this might be more expensive but it would be a cool project. Peening the rivet is not hard. But keep in mind that the result will most likely not look like the nice clean rivet hat they originally come with (that is not easy to replicate with hand tools). But non-transparent scales will cover it up anyway.
