Ties and accidentals look a bit messy, how to make it neater?

Okay so I am composing a piece for a trio. And what I am trying to get here is like a tied chord except in the next measure, each B becomes a Bb. I have seen what look like ties used to represent a half step slur if you know what I mean.

Here is what I started with:

G major chord tied into the next bar, super simple. And yes, if you haven't figured out already the top and second lowest staves are both treble clef and the second highest and lowest staves are both bass clef so you have this:

Treble
Bass
Treble
Bass

And here is what it looks like after editing to make the second B in each staff into a Bb:

The third staff down looks quite messy with the accidental overlapping the tie. But also the tie markings are gone on the notes that have accidentals in the second bar. That means I would have to use the S key on those notes right(S for slur) if I wanted those lines for the B to Bb motion? But how would I adjust the third staff down so that it doesn't look messy with the accidental overlapping the tie? Use the X key to flip the direction of the tie?
