OK, <cracks knuckles>, if you're really game to do this, it involves manually editing the saved game database,
heres the process that worked for EAW, I haven't tried it with SFC3 yet
===
EDIT: Just tried it for SFC3, and it works the exact same way, the only difference is the file you want to backup and edit is
Saves\YourCampaignName\Sfc3Spd.sds
===
(1) Get a decent hex editor and make sure you know how to use it, there's a decent freeware one at:
http://www.chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm(2) Load the game as it currently stands and make a note of your prestige, exit the game
(3) Go to folder MetaAssets\db\saves\YourCampaignName and make a backup of file Sfc2Spd.sds
(anytime you're manually editing the db there's a decent chance you're going to mess up and make the campaign unplayable,
so backups are important)
(4) Use the hex editor to open the file Sfc2Spd.sds
(5) Do a search on your ship name, e.g. my ship is the "Tikka Terror", so I searched for the string "tikka"
(6) Look a little ways past your ship name, and you'll see your in-game name
(7) About 4 characters (8 hex digits) past the end of your in-game name, you'll see the hex numbers which represent your prestige. These values are represented in hexadecimal, but the left two hex values have been swapped with the right two.
For instance, my prestige used to be 14920, which in hexadecimal is 3A48, so what shows in the database is 483A
You can edit these to any value you like, e.g. FFFF gives you a prestige of 65535
(8) Save the file and restart the game, loading your modified campaign
(9) If the game won't load then you've messed something up, so replace Sfc2Spd.sds with the backup you made and try again

PS: If you really feel like modifying campaigns in progress, you can edit alliances in a similar manner.
Search for the word "politic" and start looking for hex values (with swapped chars again) that represent the current political relationships, then replace them with the new desired relationships. After making backups of course
