I saw an interesting thing that echoes this idea. Rav Bergman in his second volume of Shaarei Ora (page 293) brings the following from a Rokei'ach; I didn't find it in any Rokeiach, but I did find it in a different sefer. In Parshas Eikev. The Ribono shel Olam told Moshe Rabbeinu that his breaking the luchos had a positive aspect.
ואכתב על הלחת את הדברים אשר היו על הלחת הראשנים אשר שברתand Chazal (BB14b) darshen
אמר ר"ל אשר שברת אמר לו הקב"ה למשה יישר כחך ששברת
This sefer says pshat is that the first luchos were written by Hashem baal peh, which, while necessary, was not optimal. But once Moshe broke the first luchos, Hashem wrote the second Luchos mitoch haksav- from the letters that were floating around in the air from the first luchos.
I did not make this up. I saw it in the Beis Shlomo, who brings it from the Ir Binyamin on Maseches Gittin, eleven lines into the first column, who brings it from a pirush on the Zohar that I haven't found yet, who brings it "בשם גדול אחד." I'm sure it's in the Rokei'ach too, but I have not found it yet.
