Interesting!
If it works like I think it works, the second screen is a regular character creation screen that uses one of the actual henchman characters that are in the game. (You cannot recruit more than 10 henchmen because there are only 10 characters for them in Cyseal - 'hidden' below the Lighthouse ;-)
In that case, it could theoretically be possible to create a party of up to twelve characters. (Plus additional companions without any code change.)
I do not know if it would be even necessary to use the SixManParty extension for that, because that only controls the number of possible recruitable companions.
All characters placed in Cyseal except the two source hunters have the 'IsPlayer' checkbox in their character sheet unchecked, so they are missing some stuff the source hunters have.
(The two source hunters have absolutely nothing special except this one flag in their template. In the final game scene, their templates are even replaced by Imp character templates.)
Would be interesting to test what happens, if one added more than two 'real' players and put them all into the character creation screen ...
Until now I could never imagine how 4 characters and their stat overview would fit onto the screen, but if it is done pair by pair ....
If I guess right, to enable six players in creation, you need no six man party mod at all (except for the balancing changes maybe) but only need to change the above mentioned 'Number of Players' in the mods meta from 2 to 6 (or from 4 to 6 when using the 4 Player mod as a base.)
In the Editor you can actually create your own mod and do nothing but change the mod's meta info, that is
Starting Level - 'Character Creation', Menu Screen - 'Menuscreen_Cyseal' and Number of Players - 6, save, activate the mod and test ;-)
If I guess right, this would add 6 characters into char creation and without any further change will allow you to recruit two additional companions ... because that is in the games story code already and would have to be changed.
