For the most part .....Sure it can.
can I re-wire this so they are on different switches? Is this possible?
This would involve some rewiring and new wires run to accomodate the new arrangement ..... how easy would depend .... if there is an attic above the ceiling this would simplify the process and minimize the repairs.... if there is no attic above then it complicates things and would likely require repairs to the ceiling.
There may also be the consideration of needing a change to the junction box especially where the chandelier would be located. The weight of the fixture could exceed the rating of the existing junction box and would need to be changed for one that is rated as such.
Hope this helps.
