Negotiating a special levy exemption

Hi there. I am an apartment owner putting together a proposal for replacing my 1970’s doors and windows (common property). I realise that I will require a by-law, and that the doors and windows will then become my responsibility.

As I would be bearing the cost of this upgrade and all future maintenance, it would seem fair that I be excluded from special levees resulting from any future strata upgrade of doors and windows (as there would be nothing to upgrade for my apartment). There is currently nothing in the 10 year plan for this kind of upgrade, but it would have to happen eventually, and could be added in at any time.  

An exemption seems fair to me, but I don’t know much about how stratas work. Do you think such an exemption is likely or even possible? Thanks.
