Hexagonal MAKERIGHT60DEGREES and 120 - cards, not grid

[kimcosmos]

I am ok without a hex grid but I have a strategic game played like dominoes with hex tiles.
Is it a big job to add these rotations? Is much dependant on the rotations other than templates (which would not be affected). Would it break tilt for example?

The game I want to play is an existing open source permaculture card game. The cards' edges face each other to match a choice of 6 inputs and outputs.
What language is the source code?
Is there a way to substitute cards in a macro? Switch card 'name'+% (1 to 6)? So I can use 6 decks with identical cards rotated and numbered 1 to 6
