Is it possible to setup two 3200 controllers to double the maximum allowed AP's from 32 to 64.
The disitributor didnt have any 3400 in stock, but he had plenty of 3200.
Is it possible to configure them in some kind of active-active cluster to split the users equally over both units?

There is no way to automatically load balance users across controllers, but you can use two 3200s to get 64 AP support.
You would have to configure one as a master and the other as a local, create two AP groups, assign controller #1 as the LMS IP for the first AP group and controller #2 as the LMS IP for the second AP group. When you provision an AP into AP group 1, it would use controller 1 as the local. An AP in AP group 2 would use controller 2 as their local.
You need to take things like seamless roaming (especially if you have VoIP phones) must be considered.
Overall, it is doable, but if there is any way you can get your hands on a 3600, that would be preferred.

Thx for your reply, that could work if the scenaria was a bit different :), I already have a master located else where. This installation as to be a local one using my master at the central site.
Is it possible to use "Local redundancy - Active-Active" option.
Setting up a Virtual route with controller 1 as master for vlan x and controller 2 as backup for vlan x (weight controlled)
Then set up another virtual router with controller 1 as backup and controller 2 as master for vlan x (weight controlled)
But that is only for one of 4 vlans, is it then possible to use the same virtual Router IP from the above router or is it somehow possible to assing multiple vlans to those routers?
The best solution would of course be to use a 3400 controller, but... :( i cant.

You can use VRRP to provide redundancy, but you have to have enough capacity on each controller to handle the full load of APs, which it doesnt sound like you have.
