Hi Reginald,
your idea is very interesting
One question, you said that the bases will be the same for the whole season for each team : but will you allow yourself re-tweaking/fix them during the season, or will you let it exactly the same form the first day to the last one, perhaps to simulate the tiredness of the players after many weeks of play ?
The total weight is also a great idea. But I understand what you means, it should be difficult to use in competition. It's the kind of "what is not forbidden is allowed" problem, too many special rules or opened rules always occurs some players to search for the perfect combo (same thing in classic miniatures figures wargaming, or slot car racing, for example), away from the true spirit of the particular rules.
I guess it depands of the players group, and the objectives of them. Like in slot car racing, some people runs "stock version" cars, other races "free class" cars where almost everything is allowed. I think both are respectable, as long as all players involved has the same objectives.
Anyway, I'll bookmark this topic too, for my own solitaire league. As a complete newbie in EF, and -I beleive- a pioneer on this side of the pond, creating a little solitaire league will be usefull to pratice in the mean time I'll search for game partners here (even if I already found another player for regular playing on monday evenings!)
