Looking to do something like this:

If anyone knows the best way, I'd appreciate the insight.

Thank you,

I see an attachment w/ a system brace between two staves.

It's not easy.  I can give you pointers for what to fiddle with but as for the fiddling, I won't be able to be of much help.

You can create a TextScript using a glyph from the feta-braces font combined with a boxed markup.  Set the Y-extent property of the text script to a pair representing the height of this stencil (you can get this height directly from the stencil).

Then, for the stencil, use the actual stencil but translate it by a certain amount.  The amount is what's difficult to glean.  You'll have to get the VerticalAxisGroup of the staff above the staff with the TextScript.  You can (probably) find the distance between the text script and the vertical axis group above by finding the height of the lower of the two skylines in the vertical-skyline pair via ly:skyline::get-height at the script's X coordinate.  Something like:

(ly:skyline-height (ly:skyline-pair::skyline (ly:grob-property grob 'vertical-skylines) DOWN) x-pos)

Where grob is the VerticalAxisGroup of the above staff and x-pos is the x position of the text script.

To get said VerticalAxisGroup, get the root vertical alignment of the score by find the Y parent of the grob until you hit a grob w/ no more Y-parents.  This is the vertical alignment.  Then, get the 'elements object.  The VerticalAxisGroup you want will be in this list (likey before the VerticalAxisGroup to which the TextScript belongs).

If this reads like Sanskrit, it is because I am tired and unfortunately don't have time to create a code example.  I may be able to in the next couple days.
