There's no practical way to put Java 5 on a Mac before 10.4. It would be
simpler and cheaper to upgrade the older Mac to 10.4, e.g. buy Tiger
CD/DVDs on ebay.
There's no way to evaluate the possibility for library conversion without
knowing what the libraries are.
In any case, you'd almost certainly need the source for the libraries.
Beyond that, it depends on how much of Java 5 the libs actually require.
That can be anywhere from negligible (i.e. the lib source is 1.4-compatible
but was compiled for Java 5) to pervasive use of features only found in
Java 5 (e.g. generics, varargs, etc.).
Practicality also depends on whether you're talking about a machine you
have complete control over, or whether you're talking about a generally
released software product. You can upgrade your machine, but you can't
upgrade other people's machines.
