How would I make a transition from one script to another, then remove the original script?

I've been working on a different method for my game instead of lumping everything all into one Master Script(It isn't bad, but I wanted to switch things around a bit more.)

So basically, I have ScriptA.

while true do

-- Random Stuff here

wait(1)
Owl = game.Lighting.Location.ScriptB:clone()
Owl.Parent = game.Workspace
wait(1)
game.Workspace.ScriptA:remove()

So ScriptA is located in the Workspace, and I am moving ScriptB to the workspace from the lighting. Now my problem is, I am trying to get rid of ScriptA. Disabling won't do(It tends to pile up ._.)

And ScriptB technically does the same thing as ScriptA(Does stuff, then moves onto ScriptC)

-Thanks!

I have an idea. Disable ScriptB, then before ScriptA commits suicide, (use :Destroy() instead) enable the clone of ScriptB. Voila?

while true do
--Whatever here
wait(1)
Owl = game.Lighting.Location.ScriptB:clone()
Owl.Parent = game.Workspace
return false
