You can't carry two silver swords, and there is no storage in the middle of Act 5 (just Dandelion at the beginning of Act 5 and the beginning and end of the Epilogue).
You would have had to store Aerondight with Dandelion at the beginning of Act 5, and retrieve your silver or rune sword that you had cunningly stored with the Act 4 Innkeeper for just this purpose, then discard that sword when you receive Moon Blade.
That way, when you see Dandelion again at the beginning of the Epilogue, you can choose whether to carry Aerondight or Moon Blade for the Epilogue; the other will be in storage at the end, and you can choose which to carry for your final save.
What I don't know is whether stored items are imported to TW2, or whether TW2 will even import two silver swords.

All desire to shirk,
Shall during off hours exhibit his powers
To Madame Tussaud's wax-work.
