You can add rules programmatically to an existing KieBase, but you have to:
1) add/replace the resource in the KieFileSystem
2) Cast the KieBuilder to InternalKieBuilder and use the
incrementalBuild() method
3) Enjoy and report problems as this is a newer feature
See the test suite here
https://github.com/droolsjbpm/drools/blob/184765346e998430064a4935fbb358930946d82c/drools-compiler/src/test/java/org/drools/compiler/integrationtests/IncrementalCompilationTest.java
the latest tests show the use of the incremental builder

I'm bumping this question for general interest on other possible solutions,
and to give my two cents.
The closest I was to getting this feature in Drools 6 from the public APIs,
is to use a persistent session. Then, when I loaded an existing session, I
would pass a newly created KieBase, like this
KieStoreServices kstore = KieServices.Factory.get().getStoreServices();
KieBase kbase = ...; //create a Kie Base
Environment env = ...; //create an environment
KieSession ksession = kstore.newKieSession(kbase, null, env);
Integer sessionId = ksession.getId();
KieBase kbase2 = ...; //updated Kie base
KieSession ksessionReloaded = ks.loadKieSession(kbase2, null, env);
ksession and ksessionReloaded would be the same working memory and agenda,
but the kie base they work with would change.
Hope this helps, but I hope more for an alternative
