Convert a alu/carbon road frame to fixed... Dropouts?

Hello, i have a question on dropouts! I have this alu bianchi road race frame, wich i want to make fixed! It has an carbon standing rear fork, wich are bolted on the alu dropouts. Is it possible to weld steel dropouts to the alu (laying) tubes? Should i buy alu dropouts with removable steel inserts? or should i just get a thick plate of aluminium somewhere and try to saw out and drill my own dropouts? What would be the way to go here?
