Close order foot are 75% the depth of open order. So for example if using 80mm widths then open order infantry are 40mm deep and close order would be 30mm deep. The depths are covered in the rulebook as well.
I have bunch of individually based models on 25mm round bases, cav on 25mmx50mm. Is there a way to transition those to Triumph well? For close order Infantry, i can't get 4 models on a 80mm base.
Yes, there are players that use their individual based miniatures on appropriately scaled movement trays to play Triumph! I recommend magnetizing them in some way or using double side foam tape to make it less painful to move them around. If your base is a little too deep, just keep in mind it does impact some aspects of the game like falling back. If possible try to make the movement bases to the same proportion as shown in the rule book, even if you have to go wider. Consistent width and ratio of width to to depth are the most critical aspects. Also make sure your group is using the same convention.
