Representing diffrent numbers of regimental cannon

[DanielS]

I'm current working on a couple of late war TYW scenarios, a question which has arisen is how the represent the fact that a Swedish brigade often had far more regimental cannon attached in support than the opposing Imperial battalions, Imperial battalions had to make do with 2-3 cannon while facing Swedes who had up to 6 cannon in support. A real diffrence in firepower which needs to be represented in the scenarios.
Is there a good way to do this using the existing rules for regimental guns or do I need to start tinkering with house rules?

Daniel,

would it not be as simple as having an extra dice to represent double the amount og guns? Then of course an extra gun model!

Or

a) Ignore the Imperial RG

or

b) Make the Imperial RG reroll a hit.
