Short form: There's no easy to do that ATM. The whole synchronization process when working with transient cores (i.e. synchronizing on some of the internal structures is pretty hairy and would require you to fork a version of Solr to change.
Much of this is being worked out in SOLR-8906 where you can have your own transient cache plugin. There are some edge cases that need to be taken care of in SOLR-10008 and SOLR-10009, particularly the CoreDescriptor (which is the in-memory form of core.properties) has some issues with multiple copies being kept around so directly writing core.properties has some gotchas currently that should be fixed in the above.
