The only concern is that in doubles you get alot more flexability at 1000 points.
This might be addressed by saying that at least 1/2 the points need to come from core troups.
I think you'll find that there are not going to be "core" troops. As for flexibility that depends on what the list maximums are - you may not actually have that many choices.
 
I think for "core" we should read "troops of a type which are compulsory".

Also, as we have seen in DBM, there is the creeping effect of inflation on competition army sizes. When we started 25mm tournaments on 6x4 tables in the South West, initially the armies were 300 points. This gave a well balanced game. However, people complained that they did not have enough variety in their armies etc, and the points gradually crept up to 325 and then 350. Then the "Worlds" at Derby went to 400 points and that is how it stuck for several years. It was too many points and made it impossible to achieve anything with a cavalry army. 800 points AoW is more like 430 points DBM.

For 25 mm 800 AOW = 430 DBM.  This favours infantry too much. 300 DBM gives a well balanced game, and equates to about 550 pts AOW. However, 550 points won't be popular:

The main reason people wouldn't want to play it at that size is that they would only get about 8 BGs to play with. There are several reasons why that would be undesirable, including the feeling of not enough maneouvre units for interest and an increased effect of luck as loss of each BG becomes more critical. ... I cannot see 25mm players being willing to stick a 532 points. If nothing else, it would mean that a substantial proportion of their figures would have to stay in the box.
Well, I suppose we could address the "figures in box" problem by running 2-list tournaments. On the other hand, smaller armies makes things cheaper for new entrants to the hobby. 
The main problem seems to be that small armies are needed to allow cavalry a chance, but small armies don't work because of scaling issues in the army lists connected to BG size. The obvious solution to this would be to reduce the minimum BG size (possibly only for 25 mm, but would people want to use smaller BGs if they were available in 15 mm?) so 4 becomes 2 or 3, 6 becomes 4, 8 becomes 4 or 6. (i.e. aiming at 2/3 the bases so frontage in mm is maintained) It may be necessary to allow some odd numbers in this case, at least for types that fight in a single rank.
From the DBM experience above it seems that players are not satisfied unless they can spend half their points on optional troops. 
If you do go down to 550 points, that means only 275 pts of compulsories, which is too low for a 15 mm 1000 pt doubles army. There would be a good case for imposing additional constraints such as sagji suggested.
It is also worth bearing in mind that there are at least three kinds of compulsory troops:
1. Those you would not take if they were not compulsory (e.g. legionaries in DBM 3.0)
2. Those you would take even if they were optional (e.g. legionaries in AOW)
3. Those which have options to be different things (e.g. Foederati in DBM Patrician list as warband, irregular knights, regular knights or regular auxilia)
and two kinds of optional troops:
1. New kinds of troops
2. Greater numbers of the compulsory troops
so a players acceptance of levels of compulsion will depend on the army they are using.
I think before asking the question "How many points on compulsory troops?" we need to know the answer to "What is the aim of making things compulsory?"  When we know that, we can think more rationally about the mechanism for compulsion and only then worry about the details of points or proportions of troop types, which may not be the same for all armies. 
So what is it that you wish to compel?
