Yet another basing question - infantry

[Conscrit]

My copy of the rules is on order from Amazon. Pending their arrival, I'm been thinking about how to go about rebasing my existing 15mm infantry. My understanding is that the standard infantry basing is double rank (four across, two deep), on bases measuring 40mm wide and 30mm deep. I would prefer to base my figures in a single rank, on bases 40mm wide and 20mm deep. Will that work? Would it cause problems (other than the obvious difference in appearance) in a game where another player had figures mounted according to the standard basing?

This is my Spanish army in 15mm and I only use 6 figures per base and the bases are 40mm by 30mm and NOT 40mm by 20mm as in your post mate
