Just in case anyone searches these forums for this kind of thing, I let you know what I went with.
I found an example of what I was looking for:

David Cribbin was so kind as to explain me his procedure and this is what I ended up doing:
1) I went to photoshop and typed a text.
2) On a new layer I traced the text with the brush tool (thickness as desired) using my wacom graphire pen
3) On yet another layer repeat step 2
4) delete original text layer
4) Import the two remaining layers into AE
5) alternate the layers every 3 frames
6) voila
