It is not big problem to open fdb file and write into its header needed big values for Tx counters.
The real difficulty is to create multiple pages with type = TIP, with filling them and also to add references to them in RDB$PAGES (one *need* to create such pages otherwise bugcheck "cannot find tip page (165)" will raise).
This task looks impracticable, at least for nowadays.
