How to store some process variables elsewhere?

The values of the process variables are stored in tables ACT_RU_VARIABLE and ACT_GE_BYTEARRAY.
Is it possible to store some of these variables elsewhere?

Some of our process variable values are already stored in our own tables.
To save table space we currently examine the possibility of eliminating redundant data.
One idea is to intervene persisting of variable values.
We found VariableScopeImpl.createVariableLocal() as a central point between Activiti and the database.
Since this is an internal class of Activiti it is surely no good idea to modify it.

Is there some other alternative to achieve the goal?

Kind regards,
