Applying a WMI Filter to a GPO that is already linked

I have a GPO that installs a piece of software. This GPO is already applied to most of the OU's in our AD structure. I need to install the same piece of software but for 64 bit machines (a 64 bit version) that co-exist in the same OU's. Therefore I thought the best approach would be to aplpy a wmi filter to the existing policy that only installs the 32 bit version to 32 bit machines and then I could create another policy with a wmi filter to install the 64 bit version.

For clarity I have not yet created the GPO to roll out the 64 bit version but as the 64 bit and 32 bit PC's will co exist in the future I thought i would firstly need to update the policy that is already applied to use a wmi filter. (If you follow). The filters are below

32 bit WMI filter: Select * from Win32_Processor where AdressWidth ='32'

64 bit WMI filter:  Select * from Win32_Processor where AdressWidth ='64'

Anyway when I add the WMI filter to the GPO that is already live when the Group policy refreshes on the affected PC's the software stops working and when they reboot the software is uninstalled (I have uninstall software when it falls out of the scope of management ticked).

So therefore it would seem that you cannot apply a WMI filter to a policy that is already linked?

Is there a way around this?
