Can I switch to Hanafi madhab only for ease? Will I need to make up for not correct according to Hanafi madhab prayers?

I have always followed the Shafi'i madhhab. However, now it seems to me that the Hanafi madhhab will mostly be easier for me. Can I now follow the Hanafi madhhab only because it seems to me that it is easier? Also, do I need to make up for prayers, ablutions, performed correctly according to the Shafi'i madhhab, but not correctly according to the Hanafi madhhab, for example, if I bled because of a cut, then I did not renew the ablution because I followed the Shafi'i madhhab and did the prayer with such ablution, now if I follow the Hanafi madhhab, do I need to make up all such prayers, after all, in the Hanafi madhhab, if blood flows from the wound, ablution is violated?
