TYW clever basing for various rules sets?

Hi, I'm currently pondering how to base my TYW armies. Primarily, the rules system I'm looking at is Warlord Games' Pike&Shotte which puts little restriction on the player in terms of units frontage and my plan was to just use 40x20mm bases. Something like this:

Musket: 2 bases of 40x20
Pike: three to four bases of 40x20, maybe six for large units
Heavy Horse: four (maybe five?) models a base, based like infantry (40mm front), three to four bases a unit
Light Horse: three (maybe four) models a base, 40mm frontage, three to four bases a unit
Artillery: Not quite sure, possibly something round for guns attached to infantry batallia and 40x20mm bases for batteries, depending on how much space the crews and equipment require.

It's probably not the best for accuracy but it's rather simple and I won't have to bother with variying base sizes across the armies. Now my main questions are: Will this work for other systems as well (DBR, Father Tilly, Basic/"Full" Baroque, FoG:R, ...) or do you have any suggestions on how to base these models so it makes a bit more sense? Secondly: Should I stick to basing cavalry with a 40mm frontage per base or should I base them alongside? I did quite a lot of Warmaster commission painting in the past and the clients mostly wanted their cavalry to be based alongside rather than with the wider frontage. Which do you think is more practicable, common and last but not least accurate?

So this is my plan for now. What do you more seasoned and knowing 10mm people think?

Thanks very much in advance.
