This appears to substantially misunderstands the purpose of the mempool
broadly in the network-- it's purpose is to model what will get mined.  If
you're not doing that you might as well set blocks only.
Significant discrepancies are harmful to the system and promote
centralization and fail to achieve a useful purpose in any case.  What
marginal benefits might be provided do not justify building and deploying
the technological infrastructure for massive censorship.

If you think this is important, I advise you to select another
cryptocurrency which is compatible with such authoritarian leanings.  --
though I am unsure if any exist since it is such a transparently pointless
direction.
