Sounds good. Obviously anyone coming from abroad would probably have a bigger say in when to hold it, seeing as it would be mostly indifferent to locals. Why don't you start by saying when it would be good for you instead: would April or June work (June might be better as more notice), but we could look into later in the year, perhaps even coordinating for the weekend before/after the famous Buenos Aires Cow-do, if anyone wants to take a week off to do both locations...
