decide is how detailed it needs to be;
not teaching you to suck eggs, but have you considered a pre-emptive executive summary or a matn of sorts, with main points before the release of the detailed work - a sharh perhaps? you of course would have come up with a skeleton for the main topics and refutation points to be considered.
this is one thing i've noticed with wahabis and devbandis, since a very long time - they offer the awam easy to digest (from literary perspective) "pamphlets" and "booklets" that the awam then latches on to. dun worry, i'm with you on the need to be holistic and comprehensive and this is something that needs to be beaten into the awam - deen and 1400 yrs of scholarship can't be squeezed into tweets like those idiots do! yes we have concise mutun, but serious students and scholars spend lifetimes expanding on them too.
anyways, the awam mainly, theirs or ours, rarely reads in depth. pick up a random wahabi (especially a desi one) and ask him to look up something in al-Aqidah al-Wasitiyya or Majmoo3ah al-Fatawa of ibn Taymiyyah and watch him get stumped. same with a Sunni and Fatawa Ridawiyya.
both desi and Arab wahabis have done more damage to awam with their "pamphlets" and "booklets" on "qubooriyyeen" and "soofees" than with this ehsan-faramosh's jahil book!
just some food for thought for you from the awam side of the table.
