I don't think so. See the CompRules:
702.36a Amplify is a static ability. "Amplify N" means "As this object enters the battlefield, reveal any number of cards from your hand that share a creature type with it. This permanent enters the battlefield with N +1/+1 counters on it for each card revealed this way. You can't reveal this card or any other cards that are entering the battlefield at the same time as this card."
The reveal limit is not a reminder text; it's an official part of the ability, which wouldn't make sense if the card couldn't be in your hand when amplify is applied.
And next, please have a look at one other card that has an amplify-like ability:
Arsenal Thresher:
As
Arsenal Thresher enters the battlefield, you may reveal any number of other artifact cards from your hand.
Arsenal Thresher enters the battlefield with a +1/+1 counter on it for each card revealed this way.
5/1/2009 If multiple Arsenal Threshers are entering the battlefield at the same time (for example, if
Warp World is resolving), you may reveal the same artifact cards from your hand for each of them.
5/1/2009 If
Arsenal Thresher and another artifact are entering the battlefield from your hand at the same time, you may reveal that other artifact for
Arsenal Thresher. If that artifact is a second
Arsenal Thresher, you may reveal each
Arsenal Thresher for the other.
In other words,
Arsenal Thresher doesn't have the exact wording for amplify, so it has to specify that you must reveal OTHER artifact cards (otherwise you could reveal itself when it enters the battlefield from your hand), and you CAN reveal an artifact that enters the battlefield at the same time since the clause that forbids it for amplify is missing.
