You could absolutely do it, but it would have the exact same limitations, it would only display the valid ones, so if two posts matched, you'd see two posts until you tried to scroll. Could work alright, but would be SOOOO much smoother if we could pull fresh posts from the blockchain with steem-rpc and filter and merge them into the feed as it loads.
