provided process is followed, a motion can be reput to the OC at any time, even if it has been defeated before.
You may also want to consider that an upgrade will be cheaper than a replacement. To my mind that argument alone may be influential in a revote.
If you feel that the views of the majority of owners is not represented by tha SC, organise as many other owners to vote at the meeting to vote down the changes
