changing mazhab

Q: I normally follow the hanafi madhab however I wish to follow the shafii madhab with regards to wudu as i read that the shafii madhab does not consider wudu broken if blood or pus or other liquids flow from anywhere but the front and back passage. I am in a difficult situation due to blood/liquid flow and would like to follow the shafii ruling. Is this permissible? Also if I follow the shafii madhab with regards to wudu, must I follow it with regards to prayer and ghusl as well? If so, what are the obligations of prayer according to the shafii madhab?

Q: I would like to ask if it is okay to follow Imam Abu Hanifa in some aspects and Imam Shafi'ee in some aspect also? Or should we follow the rulings of just one Imam?

Q: If any one follows Imam Abu Hanifa and he knows hanafi fiqh very well. If he leave his fiqh with one reason for hurmat-e-musaaharah and follows another Imam, if he prays namaz and other worship according to another fiqh, his namaaz and worship are accepted or not?
