Alaia blank question

I'm building an alaia out of pine and i was wondering if it would comprimise the integrity of the blank if I used two 1X 12 peices of wood as opposed to 3 or 4 boards of the same thickness but shorter widths.  This is my first alaia and I am doing it out of pine so If I make a mistake, it won't be on something expensive like paulowina.  I plan on getting paulowina for my next build.

Thanks!
