Copper and brass are better.
Electrical wise with all things being equal it sounds like you need to make a hybrid dripper. Hybrids ( not direct connect/hybrid top) real hybrids can't be beat for current flow

If you really have a new concept go for it, otherwise your just trying to reinvent the wheel. Most true hybrids also come with a top cap so you can also use it as a regular mech..
Many of the mods today are all the same design anymore.
Two of the best. The brass/copper nemesis and the brass poldiac have some of the best current flow measured with almost no voltage drop
