How do I add eras to maps from modpacks?

[Sniggyfigbat]

I have installed the Conversion Pack, its 2.2 patch, the SWBF2 Remaster (1.5r2), and BattleFront Extreme 2.2. (And, as part of these, I'm pretty sure I've got Unofficial Patch 1.3r130 installed).

All these are now working and they're pretty cool. There's a problem, though: I can't use BattleFront Extreme's improved/overhauled eras in Conversion Pack maps.

I have a hex editor, an install of the mod tools with the vista patch, and a dream. How do I add the BFE eras to the BFC maps? Overriding the original eras is fine; the BFE ones are better.

Could anyone walk me through this or point me in the direction of a helpful tutorial? I found this forum thread which suggests that such a thing might not be impossible with the use of a hex editor, but I don't understand the .lvl format enough to work out what to do.

Any help would be much appreciated!
