This also applies to your proposal. 51% of miners can reject all "status quo votes" and blocks containing status quo votes. After one year, these status quo votes will get lower and lower weight and eventually the blocksize will be increased.
Rejecting transactions that are not accompanied by votes would be logisticly difficult. When you send a transaction generally only one of the outputs will be owned by you, often none of the outputs at all, so unless miners are willing to make it impossible for you to send funds to someone who is off-line or simply does not wish to vote they will be unable to coerce votes in that way. We can and should further strengthen this protection by having all nodes only relay votes for outputs of confirmed transactions, never unconfirmed ones.
