I can't say for sure but I'd bet a dollar that you can install it, it's an accessory alignment issue.

NAF,
I'm sure you know someone that could have answered these questions for you.
LS7 and LS9 damper can't be used on the LS2 crankshaft. LS2 crankshaft is short snout for wet sump engines. LS7 and LS9 dampers are designed for long snout dry sump configuration crankshafts.
The LSA damper is for a wet sump engine (short snout crank) so it can be installed on an LS2 crankshaft without any issue. The LSA damper is designed for a keyed crank and the LS2 crankshaft is not keyed. You can run a keyed damper on a non keyed crank (or the other direction too) , you just can't use a key. You can pin he LS2 crankshaft using the ATI crank pinning kit and then the LSA damper would have a pin engaging in the keyway.
The LSA accessory drive has the primary accessory drive offset from the Corvette engine so that is the same the 2004-2007 CTS-V. The dedicated 8 rib supercharger drive pulley is forward of the primary accessory drive so that makes the damper fairly large and in many vehicles not designed to fit the LSA engine it often interferes with something in front of the engine.
BTW - just a side note while discussing LSA dampers, in case anyone buys an LSA crankshaft, keep in mind the LSA crankshaft is an 8 bolt flywheel flange while other LSx engines are 6 bolt (other than the LS9 which is 9 bolt). Some of the GMPP crate engines are also 8 bolt cranks. This impacts flywheel, flexplate, clutch selection etc.

I am runnin a ls7 drysump system in my 05 with 06/07 ecm.
I am uncharted territory
