It was basically sword - greatsword - spear - bow. Then there were rods, boomerangs (throwable swords), and a bunch of goofier things that were gimmicky versions of the main four. The different versions were stronger/weaker, had elements or special (crushing) abilities, etc...but that was basically it.

I don't know how fusion works in Tears, but I wouldn't be shocked if they gave you a 'Master' version of the big four and you fused something to it to give it one of the added abilities either temporarily or until such time as you wanted something else. You would also have to be able to make them continually stronger (probably through fusion) for some sort of progression over time. That could work.

The main problem with doing something like that is that they added durability to BotW primarily such that you would want/need to find weapons in the world. There are many fewer interesting things to find in that big world if you don't need new weapons constantly. Can fusion materials be exciting enough to fill that the void? Something else?
