To reverse or not to reverse

[Rich#6]

So I am rewiring a carvin with a HSS pickup config. the bridge is going to be a evo 2, the neck is going to be a seymour duncan SSL5. the middle was going to be a lil59. it doesn't fit the skinny carvin pickup slot so I have to go with another single. do I go with a reverse middle single or since it's a humbucker at the bridge reverse the bridge pickup wiring? It has a 3way switch that I guess has to go to a 5way.

If you want the no hum in the 4th slot yes do a reverse wound middle.
