Why not just keep pushing the edge of what's currently possible, and keep a catalog of the more advanced ideas that you can revisit from time to time to potentially begin executing on? For the ones you identify as still too advanced, specifically identify the pieces you still need. Judge whether or not you (or a team you know/could put together) could develop any or all of those pieces. If so, do it. If not, wait. In the meantime, constantly ask "What's the best way to solve this problem given what I can do today?" and do whatever the answer is.
