I'd just add a "Wait for 5 minutes" between 2 and 3.
Alternatively, you can generate all (x) addresses from the same wallet, export the (x) p-keys, import each of them in a new fresh wallet, and ultimately delete the first generating wallet.
I exported keys and it generated one CSV for all keys. But I don't see any import or load wallet option in litecoin-qt
Not sure about litecoin-qt, but using bitcoin-qt, you can go to help=>Debuging=>Console and use the importprivkey command there.
Type "help importprivkey" first to get the right syntax.
