Your setup violates good seamanship. You should never have a drain
connecting into the cockpit scuppers. Any possible clog could cause the
cockpit to fill and you know what happens then.

Yeah....that's the reason I've my current dilemma.

Both the forward sink, and the aft sink ran to the cockpit drain
through hull.

The forward sink was an easy fix. There was a through hull already in
place directly underneath.

The aft sink also has a through hull directly under it, but the
plumbing from holding tank and the fore and aft heads is connected to
it.

The 1/2" intake for the heads is approx 4 feet further away and I
think a bit too small to use as a drain.

I think I might try Peggy's idea of using a sump. ...the shower sump
is on the other side of the bulkhead.

It might be the best I can do...not having a first choice.
