To my knowledge Opera as of yet (at 12.11) does not use SQLite to store any of it's profile data, thus the function(s) SpeedyFox utilises don't (currently) apply to Opera.
If ever Opera Software ASA decides to start using SQLite as the/a storage method for Opera Profiles, by all means request that it be added to SpeedyFox.
In the meantime, there is little to nothing that SpeedyFox can do for Opera profiles.
P.S.: Please use more descriptive subjects in the future, they are all that shows up on the Forum's Topic Index and something like "Add Support for Opera Profile Optimisation" is generally going to get a better response than "Suggestion".
