What everyone is saying is pull the dist and rotate the distributer drive shaft / gear a few teeth.( One might be enough)
Now that being said you might be able to do the same thing by doing as you said and make a different distributer post the #1 post and rotating the dist enough to clear and time correctly.
If it was me. I would get out my Factory Service Manual and follow the procedure to set it correctly that way down the road you or another owner won't be confused.
