Having a Sorceress summoning phantoms fits thematically, and changing a LightInfantry's color to grey would already do, having more phantoms per ability should also scale well (maybe give the phantoms a small swarming bonus as well, so that they remain useful at high level, say str 10 hit 1 plus +2 swarming or so).
The only problem might be a runaway hero stack in the endgame: Currently, one can grind such a stack down over time, if it enters enemy territory too deep. The Sorceress would provide too much cannon fodder then. The fix could be that the sorceress' phantoms still have to respect the stack limit of 8 units, so that such a powerful stack may only use 1-3 phantoms anyway?!
Thanks! Still, it's easy to spitball an idea, alot more work to actually write the code for something like this.
Balance-wise, yeah it might be too good if phantom warriors could increase the stack size beyond 8. Limiting it might be necessary. Or, you could just have her summon 1 unit, but upgrading the ability increases the unit's number of wounds/strength. Or maybe have both upgrade options available.
For a slightly different theme, one could make the summons recolored versions of the Sorceress herself, and call it "Mirror Image".
