Traders (be it hedge funds, props, retail, anyone) will only "take your action" if you price competitively. You'll never get your orders filled. The open bid and ask as per whatever the exchange quotes are really the only prices that matter when it comes to what actually gets executed.
Also even if you do quote wider, to effectively capture the spread, your buy on one side and your sell on the other side still have to basically occur simultaneously which is where the demand for latency comes in so you really can't escape it.
That said there are ways to still be profitable even if you know you're not the fastest gun in the west across the most exchanges. Without going into too many details you'd have to selectively choose where/what you trade. Which is not trivial at all of course.
