I have a feeling it wouldn't be a good idea to allow changing a standard action into a second swift action. While I cannot give an example that would be obviously broken, I believe it's an important part of the balancing that there is no way to gain two swift actions.
Having two swift actions in a round also means that you could take an immediate action during another's turn and still have a swift action available on your own turn. I'm not sure I like this...
Wow - this is pretty backwards.
I think you meant:
"I have a feeling it wouldn't be a good idea to allow taking a second swift action in the place of a standard action."
I would have no problem, with it at all. I think it works well, and, in some cases, it is really dumb to
not allow it. With the caveat, of course, that it is treated as a standard action - that is, it does not avoid provoking an AoO the way a Swift Action does.
It seems very silly, for example, to do a Swift Action and a Move action and not take any Standard Action and yet have used up your Swift/Immediate Action for the round. Makes no sense at all.
You do NOT end up being allowed to take two Swift Actions in a round. You do end up being able to take two actions, one of which is a Standard Action that is eligible to be a Swift Action - which is a different way of thinking about Swift/Immediate Actions.
I think it is best to think about these three action types as a hiearchy.
All of them may be taken as Standard Actions.
A smaller set of them may be taken as Swift Actions, if you have yet taken a Swift Action or an Immediate Action.
An even smaller set may be taken as Immediate Actions, if you have not yet taken a Swift Action or another Immeidate Action.
