It is doable if put a lot of hooks of asking engine about tables.
There is already hooks now used in table invalidation. But it works slowly (relatively) because having no open table difficult to give engine full information and so each such hook will cause semi-open process and so if we have miss it looks like double opening overhead.
So, in price of total overhead we can make it, the question is if it help so much that gain will be more then overhead in average... As usual I have doubts about it (need a proof).
