LBZ piston replacement

Well the wifes LBZ finally let the headgaskets go, so I'm pulling heads, gonna do gaskets, studs, turbo etc but I think I'd like to do pistons while I'm in it
Question
Can I just pull the rods/pistons and put new lb7 pistons/rings on the stock rods and put new rod bearings/bolts in and call it good?
I'm looking for a good reason why I can't, as far as I can think there shouldn't be a problem, there's nothing wrong with the motor except blown headgaskets I just don't want to crack an LBZ piston, keep in mind the most truck will see is maybe 650 with the turbo (probly 4094vvt) and maybe around 40% nozzles, so I figure the stock LBZ rods and some Mahle lb7 pistons should hold up fine for around 600hp
Tell me what you think please! I don't want to tear the block down for machining I'll be at the end of my budget with pistons

it has to be balanced as an assembly IIRC. since the pistons weigh differently it will have to be rebalanced.
