stock turbos - swapping #2 to #1

Hi guys, I have a JZS161 Aristo and the front turbo compressor wheels have been badly damaged. I am going to take apart the intake system and the turbos and thoroughly inspect them. However, I have a spare #2 rear turbo and wondering if I will be able to swap them? Can I swap just the core and keep the front compressor housing and turbine housing if they are undamaged?

They are different the first turbo has a waste gate and the 2nd doesn't .  The internals might be the same but you would have to rebalance them 

If the core is the same then it shouldn't be a problem. Rebalancing doesn't arise as we wont be dismantling the core. I will try using the spare rear turbo core and swapping the compressor and turbine housings from the broken front turbo.
