[stylist] curious-would this be too confusing?

[Vejas Vasiliauskas]

Hi,
I know that when it comes to writing it's ultimately up to the 
writer, but I was wondering, if I were to publish, if this would 
be too confusing.
I have a set of characters in mind whom I created about two and a 
half years ago, so I know a lot about them.  Of the siblings I 
have created, there is one in particular whom I would focus on 
the most.  I thought that eventually if I wanted to write books 
about them, I would vary the writing styles for each book.  The 
books would cover certain periods of high school life.
For example:
- One book could be the main character's journal.
- Another book could be a multiple POV with the main character 
and any siblings.
- Another book could be written in the form of letters, from main 
character and penpal from another city/country.
I know this makes it more interesting, but would it distract 
people who are familiar with a certain writing style throughout a 
series?
Thanks,
Vejas
