Sounds like a good plan in the long run.

I like it.  I'll need to set the version of a few libs to at least 9
since I've been using 9 in Debian for 1.4.X, but I'll go ahead and set
the age to at least 1.  Is there any reason we might need more than
one level of "age" headroom you can think of?

(As an alternative to consider, couldn't we also just release a new
 version of 1.6.X with libs that have high enough AGEs to cover the
 older 1.4.X libs?  Which would be better?)

Presuming for the moment that an AGE of 1 is enough headroom, how
about these as candidate versions for everything for the release (BTW,
I'm not stuck on "15", I just chose it at random -- anything >= 11
would probably be fine too...)
