7 Day timer and variance

[Eslade]

I had a weird idea and that's why I'm posting this in RnF. Why can't we have the boss mobs do their normal 7 day timer as usual, but also add in a couple of random repops every week also?
For example
Tuesday morning All boss mobs pop.
Tuesday afternoon all boss mobs are dead.
Thursday night Cazic Thule spawns
Saturday afternoon VS spawns.
etc... etc...
Then back to Tuesday where we have the normal spawn cycle again?
Since these are technically two mobs spawning, one could have a lesser loot table and there is a slim chance that they will spawn in the same spot, IE two Trakanons.

But Ed, wouldn't this create twice the loot? Not quite double, the bosses that do an extra spawn would be random and some might not show up until their normal time. Wouldn't the population increase if there was more of a chance to get boss loot?

Anyway just thought about this and wanted to post. Go ahead and flame me, I've got my resist gear on.
