When using Flow, target surface splits

Hi All, so I've now reached the point of flowing the lattice work on the solid ring:



The next step I'm trying to figure out is how to substitute the top of the solid ring with the lattice so one can see right through it. I tried various Booleans but none produce the results I'm looking for. Essentially, I'd like the lattice shape to be the top of the ring and seemlessly merge/blend into the rest of the bottom section of the ring.

Please could someone explain how I can go about this?

One more thing! In the next screenshot, you'll see there are gaps in the actual flow. I tried to use the 'Uncurve' script to matche the width and length of the ring curves so they flow accurately along the edges of the ring but that didn't seem to work. Any guidance on this would be fantastic, thank you!

I ran out of attachment space, so here is the 3dm file:

Many thanks indeed!
