There are 2 files currently that are open for manual modifications:
https://github.com/OSGeo/proj.4/blob/master/data/sql/customizations.sql
https://github.com/OSGeo/proj.4/blob/master/data/sql/grid_transformation_custom.sql

(the DDL are in proj_db_table_defs.sql)

customizations.sql would be the appropriate one for adding custom ellipsoids.
We might revisit the structure of this in the future if they grow a bit out of
control, but hopefully the 'PROJ' authority will not have to grow too much...
