Ciphers for a simple phrase

How might one encode a simple phrase of lower-case letters? Consider these parameters and include more if you can:

1. Phrase length in characters

2. Permutation of character order in phrase

3. Number of words

4. Words character length

5. Permutation of word order in phrase

6. Character values (a space is value zero); a-z --> 1-26

7. Interchange space(s) with, e.g., previous word's first [last] letter

8. Add to letter value a particular multiple of two sequential digits from known, irrational constants like pi: 3.1|41|59|26|53|59|97|93... [e.g., with multiple one, word "alphabet" becomes "fawhbisxi" of modular letters]
